Ultrasound FAQ Reference Guide

Upvotes

As an OBGYN ultrasound tech working at the general level here's a few things I would love the community to know based on common questions I see.

Most important rule of thumb: Worry when your doctor tells you to.

OBGYN docs are going to pay the most attention to the fetal pole and heart rate. Once a fetal pole is seen, the CRL (crown rump length) measurements are gold standard.

I'm worried about the heart rate:
-Check out this resource for pregnancies dating less than 7 weeks. Make sure to refer not to your LMP dates, but measured CRL dates: https://radiopaedia.org/articles/fetal-bradycardia?lang=us
-After 7 weeks a normal heartrate is between 120-180. It can temporarily dip below or temporarily rise above this range, but prolonged time above/below will definitely get your doctor's attention especially in third trimester. Generally out of range heart rates trigger NST (non stress test) or more monitoring.
The measurements are off:
Baby measures behind LMP. This is actually pretty common, we often see dates off up to a week either direction. We don't ovulate on the exact same day of the cycle each month or even have the same length of cycle. With irregular periods, PCOS, or unknown dates even larger gaps can be perfectly fine. If you aren't sure of your dates, trust the ultrasound. Even if you are sure of your dates, don't panic if they are a week off. Ultrasound measurements in early pregnancy are +/- 5 days.
I'm in limbo and don't know if my ultrasounds are diagnostic for loss:
By ultrasound there are strict parameters to diagnose loss. No one wants to get this wrong. Check out this resource for a list of parameters diagnostic for loss: https://radiopaedia.org/articles/early-pregnancy-loss-1?lang=us
Note, there is a second list of "suspicious for loss". Keep in mind the second list is not diagnostic, things can still turn out just fine.
I don't know when I should see what on ultrasound:
Things can vary a bit from person to person and do change *quickly* in early pregnancy. Check out this resource for what you can generally expect to see:
https://radiopaedia.org/articles/early-pregnancy?lang=us
Should I go to a boutique or get a private scan? Or push for an earlier scan?
They aren't legal where I am but here's a few things to consider if you plan to book a private scan. First, what are the qualifications of the person running the ultrasound? An ultrasound is only as good as the one performing it. It sounds as if these boutiques are NOT permitted to give much/any information. Will you spiral if you believe you see bad news and they cannot confirm or deny it? Also it seems that many cannot do vaginal ultrasound, which will make seeing a baby under 7 or 8 weeks challenging. If I had the option of a boutique ultrasound I would personally wait until 8 weeks and I would book it for a weekday. If they see something bad, it is not ideal to find out over a weekend when there is no option to follow up with your doc. An earlier scan often causes more anxiety, not less. It's SO hard to wait. But if you can tolerate it wait until 8 weeks or so.
The gestation sac is small/big:
-Gestation sac measurements are not terrifically accurate. Where I work once a baby is seen the gestation sac isn't measured. A mismatch between baby's size and the gestation sac size isn't uncommon. That said, a mean sac diameter of 25 mm or more without a baby is diagnostic for loss.
The yolk sac is small/big:
It starts teeny tiny, and will get a bit bigger. Once a baby with a good heartbeat is visualized, the docs I work for don't seem to care about the size of the yolk sac. A failed pregnancy with an expanded yolk sac (more than 6 mm) is a suggestive of chromosomal abnormalities.
We don't know where the pregnancy is:
The statistically most likely outcome is either a chemical pregnancy or just coming in for ultrasound too early for visualization. Ectopic can't be ruled out, and many wise ladies in the this sub have unfortunately experienced this and can give more info than I can. Statistically it's believed that only 1-2% of pregnancies are ectopic, but listen to your body. If the location is unknown, you should be getting close monitoring and follow up until the location is known or the pregnancy has ended.
-For a resource on ectopic pregnancy: https://radiopaedia.org/articles/ectopic-pregnancy?lang=us A note, a pseudosac is visualized in only 10-20% of ectopics. Therefore a sac in the uterus is suggestive of intrauterine pregnancy but can't be proven until a yolk sac is also present.
What about my HCG numbers?
I'm not an expert on this at all. But here's a resource: https://radiopaedia.org/articles/beta-hcg-1?lang=us
Why didn't my ultrasound tech tell me anything? And/or why were they so optimistic? Or, I had an ultrasound in the ER and they were very pessimistic.
Many locations an ultrasound tech can very much lose their job if they say aNyThInG. Where they are permitted to say certain things some ultrasound techs may just be hoping the best. We work with the public and we have seen some wild stuff. Additionally no one wants to call it a loss unless its 1000% certain. We know how devastating that news is. A side note here, often an ultrasound in the ER is not an ideal experience for the patient. The ER is staffed with techs that are much more versed in gallbladder and liver scans than they they are early pregnancy ultrasound. Don't hesitate to go the ER if you are having concerning symptoms, but do know the ER doc will make sure you aren't actively dying then will likely refer you back to your OB for follow up.
I'm just so anxious about it all:
Someone awesome wrote out these mantras. Maybe they will help: https://www.reddit.com/r/PregnancyAfterLoss/comments/14uhbdg/commandments_of_pregnancy_after_loss_this_is_now/
Also a podcast I personally found very helpful with anxiety: https://www.oneyoufeed.net/russ-harris-part-1/
https://www.oneyoufeed.net/russ-harris-part-2/

Today you are pregnant and this baby is so loved. I really am hoping the best for each of you. Those of us who have experienced loss.... you didn't do anything wrong, I promise. This is a club no one deserved to be in. And you are not silly, foolish, or dramatic for grieving your little babe for as long as you need to.

This post is written in honor of Eli, who died long before I could meet him. Rest in peace, buddy. I miss you tremendously ❤️

Beta hCG Levels - READ BEFORE POSTING

Upvotes

Here at [r/CautiousBB](r/CautiousBB), we see a lot of posts on hCG values, doubling times, and trends. Please read this post before posting to avoid posting something that is not, in fact, abnormal.

1 - hCG levels vary greatly in the first 4-6 weeks of pregnancy. One value is not going to tell you much, unless it is extremely low (less than 25 by 14 DPO). The doubling time is more important!

2 - We consider hCG on the lower side if it is <50 at 14 DPO (approx. 4 weeks gestation), <100 at 16 DPO, etc. If your hCG is a lot higher than these numbers, it's unlikely that you have low hCG. If you hCG is at or below these numbers, they are considered low, but not necessarily diagnostic of a loss.

3 - Normal hCG doubling times are, in general:

  • 48-72 hours when the hCG level is under 1200 - 6000.
  • 72-96 hours when the hCG level is 6000+
  • 96+ hours when the hCG level is 10,000+

4 - Based on number 3, please consider the following:

  • If your hCG doubling is within the ranges above, it is not considered slow. Please refrain from posting something like "my hCG did not double in 48 hours" when your values are post 6000+.
  • Doubling rates WILL slow, even if you were faster than the average. For example, if you were doubling at 37 hours, a change to 54 hours as hCG rises is not abnormal and is usually nothing to worry about.
  • If your doubling is slower than the average, we'd invite you to post so we can understand the details of your specific situation.

5 - hCG has a specific job. Check out this post here to understand why hCG doubling slows and eventually plateaus.

6 - hCG values that drop and then rise again or rise at an inconsistent, very slow rate can be indicative of an ectopic pregnancy or a pregnancy of unknown location (PUL). This is a life threatening situation - please seek medical care immediately if this hCG pattern applies to you.

We invite you to continue to post hCG issues or levels for assistance, but hopefully reading this gives you some insight and a baseline as you begin your perilous pregnancy journey. We've also added some literature below to help you understand hCG levels and doubling.

UPDATE July 2026: We are locking this post to new comments - if you need input on your personal situation, feel free to post in the sub!

Happy hCG-ing! :)

Experiences with fever before 6 weeks… please reassure me

Upvotes

I lost my son to a neural tube defect back in March. Just found out we are expecting again, and as fate would have it, I’ve contracted some awful virus. I’ve been taking Tylenol at the first signs of fever, but towards the end of one dose my fever shot up to 101.7 before the next dose kicked in. It was back down within an hour.

I am already at a higher risk for NTDs due to my son’s diagnosis. I’ve been on 4mg of folic acid daily to mitigate that increase risk. I’m heart broken that the first time I’ve had a bad fever in YEARS is in the critical development period for my baby. There is a small statistical correlation with maternal hyperthermia before 6 weeks and NTDs. I do not need this increasing my odds, yet here we are. It’s done, it happened. I’m so scared.

If you had a fever before 6 weeks and everything turned out fine, will you please tell me about it? I’ll take anything to make me feel better.

Afraid of my appt tomorrow

Upvotes

I’m 18w with my 6x rainbow baby. I’m meeting with my OB tomorrow and I just know she is going to try to pressure into getting a PAP. Their office is always so rough and I always bleed after. I actually had a MC after getting a PAP there last year- idk if it was related but I am TERRIFIED.

I am not getting the PAP. I have a long history of normal PAP results and had one 2 years ago. The ACOG guidelines say I am okay, but I know she’ll try to pressure it and I just don’t understand why.

She’s also booting me from her practice bc I am too high risk (type 1 diabetes) and this will be the last time I see her this pregnancy. I just need the strength and courage to tell her no- I am not consenting to this. I need to protect my mental health and my baby right now. I feel so anxious and scared.

No heartbeat at ~7weeks and no symptoms

Upvotes

Hi! I'm writing here for the first time as I'm freaking out more than I thought and would like to hear some more experiences.. I'm 7weeks 1day today, but my cycle is about 33 days long so it could be less. I've just had an early pregnancy scan, including a vaginal ultrasound, and they couldn't see any heart beat. Unfortunately I don't know the embryo size yet (I should have asked more precisely, I didn't, but I'll have the report in a few days). The other thing is that I don't really have any symptoms - the only thing was sore breasts, but that seems to have stopped. Should I be really worried?

Extremely nervous about first ultrasound

Upvotes

I had a MMC about 1.5 months ago. Never got a period after the loss. I had been taking tests to watch the lines fade and after a vvvvvvvvfl line about 4 weeks after my loss, the line started to get darker again. Went back to my midwife for blood tests. HCG went from 100 to 800 to 3400 all within 1 week. My midwife said the logical explanation is new pregnancy. I did have ovulation confirmation on home fertility monitor about 10 days before my tests started to get darker.

We have an ultrasound planned for later this week, at an estimated 6w0d. With my MMC baby stopped growing at 6w3d. I’m just so incredibly nervous. I know it may still be too early to see a heartbeat and this scan is really just for confirming an intrauterine pregnancy at all and a later scan will be needed to help determine viability. But I can’t help but hope we’ll see a fetal pole with a heartbeat. I’m so nervous for another loss or the news that this is just some weird fluke and not even another pregnancy at all.

Positive update after suboptimal HCG rise and borderline early heartbeat

Upvotes

Wanted to share our journey as I am feeling more positive than I ever have, not out of the woods but have had encouragement from our doctors.

Posted in here almost a month ago now to say that we did HCG testing, 1 week apart and the rise was not encouraging. We went 3,600 to just under 7,200 making it a 97% increase over 7 days. We read this wasn’t optimal at all so weren’t optimistic. This was between 4w6d and 5w6d since LMP.

Following this, we had the first ultrasound not last Friday but the Friday before at 6w6d, which recorded a 119bpm, 9.4mm. The measurement also put us 3 days off LMP. We were told the bpm was a little slow, but our doctor started to show some controlled optimism at this stage.

Last Friday, at 7w6d, the bpm measured 150bpm and went up to 14.6mm across the week. The bpm acceleration was very reassuring and there were 6 days of growth recorded across 7 which was also reassuring.

Our doctor is now saying she is very reassured which has been such a relief for us.

I guess the worry we now have is that we are now 4 days off LMP but our doctor isn’t concerned and I have read this is normal.

Just wanted to share a positive story following a sub-optimal HCG rise and borderline heartbeat. This has also happened with mild/minimal symptoms. Again, I know we still have a long way to go but feeling pretty good about this one after having previous losses.

Advice Needed Small gestational sac - help :(

Upvotes

I'm distraught. Had a private scan yesterday at radiology at 7w0d.

Baby measured 6w5d, FHR of 138bpm.

But just read my report and my gestational sac measured 5w6d on the 7th percentile.

CRL: 8.9mm
GS: 12.2mm (18.7 x 8.2 x 9.8)

So only 3.3mm difference.
I do have a retroverted uterus.

I've read that <5mm can have up to a 90% miscarriage risk. I am absolutely spiralling and can't stop crying. My clinic is going to call me back soon, the nurse said that since it wasn't an obgyn who took the measurements that we need it reviewed by one.

This was an ivf pregnancy after loss from a 3 day fresh transfer and I am expecting the worst.

My doctor is fitting me in for a scan tomorrow morning at 8am.

It's not looking good, is it?

Advice Needed What could be going on?

Upvotes

Hi!!! So I am on CD 34 now and I ovulated somewhere between CD 25-27. I had a peak test last Saturday. I ovulated late because this is my first cycle off birth control. I’ve had two previous c sections last one being 6 years ago. I’ve had very intense hormones this cycle I think because it’s my first cycle off. Also pretty confident I hyper ovulated as I am 36 and had lean PCOS with my previous kiddos. I felt like I had ovulated from both sides although I know I can’t “prove” that. I was instructed to take progesterone 3 days after ovulation so I started that mid last week. I’ve had a ton of pulling and cramping, a lot being on the right side of my pelvic area. I’ve had lighting zaps in the vagina too and if I sneeze it feels like something is gonna tear. Nothing keeping me from functioning, I cleaned all day and did my normal exercise, but the pain was off and on noticeable. I took an hcg test yesterday and had a very faint positive. I tested faint positive with both my boys around 8-9dpo so it is early but I could see it. Today I’ve only had one faint positive and the rest have been negative or have a evap line. The pain on the right side is now kind of burning… I checked my charts from last pregnancies and I did list right pelvic pain as a symptom but idk.. this feels weird. No bleeding or anything. I have to go to the dermatologist tomorrow and I may ask her to just let me take a blood test to see if I’m pregnant. I am slightly worried it’s CSEP, I know that’s sooo rare but I feel like it’s way too early to have this much discomfort. Thoughts? Please be nice. Thank you!

Confused and just hoping for positive stories

Upvotes

Hi all, just hoping for positive stories. If not at least someone to hear out my stress rant. I’m 11w1d today and was diagnosed with a small-moderate SCH at 7w3d. It’s been a weird and stressful day to say the least. I passed a clot this morning and was confused as to whether or not it was related to the SCH or something more serious. I passed two more smaller clots as the day progressed. No tissue that I could see, just the clots. Here’s where it gets weird. I’ve had nausea for the majority of the pregnancy but not actually thrown up UNTIL today. I took a sip of my drink and felt the need to throw up immediately. It was so strange. Has anyone had anything similar happen to them at all with positive results? I have a doctors appointment tomorrow but it’s just been a weird day and I’d love some positive stories or just for someone to calm down this very stressed mama😣

8w4d and First US tomorrow and I am convinced it’s bad news (spotting, very little pregnancy symptoms thus far)

Upvotes

My original first US was scheduled for September 25th at about 11weeks, but since then I’ve started to spot for the last week and have talked to my doctor and pushed up US to check for viability so now I’m going in tomorrow. Husband can’t get out of work for this one so last minute so I’ll be alone and I’m absolutely terrified. I have to drive into the city for this one too as there were no local slots available. I’m afraid the drive back is going to be brutal alone and possibly crying after bad news.

My spotting started at 7w3d as brown discharge, and since then I’ve had a little bit everyday and it’s ranged from dark dark brown/black old blood, to lighter brown discharge, to pink and some red mixed in as well. Its never been enough to fill a pad, just enough to see when wiping and maybe a spot or two on underwear. No significant cramping or any pain with it. I know women spot during pregnancy all the time and it can be very normal but I just don’t have a good feeling about it, because I also have had pretty much NO pregnancy symptoms this entire time, and I’ve read a lack of nausea can be a sign of lower viability. I have had sore boobs and i still have that symptom, but the level of soreness seems to fluctuate throughout the day and I feel like that can maybe also indicate dropping hormones? Other than the boobs, I just don’t FEEL pregnant. I find it very hard to believe there’s a growing baby inside of me…

i think a week or two ago I felt more fatigued than I do now, but as a chronic night owl it’s hard to track my tiredness because my baseline is tired lol. I also felt like I’d get short of breath pretty easy about a week or two ago and now I think that’s subsided as well? Absolutely have had no changes to my eating or appetite since finding out I’m pregnant and it’s so weird.

Im just bracing myself for tomorrow. I find out I was pregnant pretty early because I had some implantation cramping at week 4 and I knew I must be pregnant so I took the test at 4w6d and it was positive, so now I’ve been pregnant and it’s been on my mind 24/7 for a full month, remembering to take my vitamins, always researching what I can and can’t eat, obviously day dreaming about baby, like I feel like my entire identity changed already internally, and now ill be back to being not pregnant, I know it’s only been a month but I feel like I don’t remember who that not pregnant girl was!!

feel free to post your experiences with spotting both good and bad

im about 6wish and symptoms feel like they’re dropping off. I was SO tired, boobs hurt, nausea at night mostly. Yesterday and today, nausea isn’t as bad….and today i have a lot more energy. boobs still hurt.

my HCG has risen appropriately but now I have to wait a whole week until my first scan.

11dpo (I think) with negative FRER

Upvotes

Hi everyone! This is my first post and I just found this community/forum this week.

I had a MMC that was diagnosed in June, but ended up naturally miscarrying in July around 10 weeks (on 7/5)… the baby stopped growing around 6 weeks 4 days. I got my first period post-MC on 8/11 my husband and I decided we wanted to start trying ASAP. These are the notes I took based on when we BD’d and when peak ovulation was:

Tuesday 8/11 AM: period
Monday 8/17: BD
Wednesday 8/19: BD
Sunday 8/23: BD
Monday 8/24: BD
Tuesday 8/25 AM: Peak ovulation
Wednesday 8/26: BD
Thursday 8/27: BD

Based on my ovulation strips and app, I think I ovulated around 8/27.

Fast-forward to today I believe I’m 11 DPO and had a negative FRER test this morning as well as this evening. With my last pregnancy, I had a VVVFL at 9DPO. I did have cramping for a couple hours this morning that weren’t painful but I definitely noticed them. Not sure if it’s potential implantation cramps, or PMS cramps.

I guess my question is: with this information is it possible that I implanted late? And I could still have a positive coming up? I know of course they say you’re not out until you get your period but just wanted to hear some thoughts.

Thank you all so much!!

Ultrasound Is there a small chance this could be a viable pregnancy?

Upvotes

Has anyone had a similar hCG pattern and gone on to have a viable pregnancy? I’m desperately looking for experiences, good or bad.
My hCG has been extremely abnormal:
• 82
• then dropped to 68
• then shot up to 247
• then 31 hours later it rose to 370
Because of the initial drop and then rise, I was honestly preparing myself for an ectopic or another loss. I went to the ER expecting the worst.
But on my ultrasound, they actually found a gestational sac AND yolk sac in my uterus, measuring around 5 weeks. 😭 They obviously can’t confirm viability yet because it’s so early, and I know my hCG pattern is very concerning.
I’m trying to keep my expectations realistic, but seeing an intrauterine gestational sac and yolk sac after thinking this was definitely going to be ectopic or nonviable has given me a tiny bit of hope.
Has anyone here ever had hCG actually DROP early on, then start rising again, and still end up with a viable pregnancy? Or had very low/abnormal hCG but an ultrasound that continued to develop normally?
I know nobody can tell me how mine will turn out — I’m really just looking for anyone who has been through something similar and what your outcome was. Is there any hope? 😭🙏

VERY slow beta, but fetal heartbeat

Upvotes

Hey all 💗 Second pregnancy, now 6+4 weeks approx. Barely any symptoms — just mild tiredness. Wouldn’t have known I was pregnant if not for missed period and a positive test.

My gut said something was off, so I checked my beta

hCG:
1. 1800 (21-22 dpo)
2. 2400 (four days later)

- Ultrasound showed fetal heartbeat

  1. 3200 (four days later - 30 dpo)
    - Heart still beating (three days after last test)

Worried about an ectopic pregnancy, I booked an emergency ultrasound after my second result.

To my huge surprise, there was something in my uterus — a yolk sac and embryo with a heart rate just over 100. And this was with a beta of only 2400.

Went back today, three days later. Fetal pole has grown 1 mm, heart still beating. Heart rate 104 bpm. A little on the

My gynaecologist is a little fumbled, she expect hcg to be at least 5000 until a heartbeat is seen.

I’m very pessimistic towards the whole situation, but I’ll of course give it a chance until it eventually doesn’t develop anymore.

Just wondering if anyone has been in a similar situation? My next ultrasound is is one week.

This limbo is hard :/

Symptoms No PMS after 2 chemicals TTC

Upvotes

My husband and I have been TTC for almost a year, we’ve had 2 chemical losses, one in January and one in June. I always have pretty intense PMS breast tenderness (my boobs fluctuate at least a cup size during my cycle), high emotions, and usually my cramps start CD 1. With my two pregnancies, I had extremely tender breasts and very vivid dreams leading up to positive tests.

This cycle, I have had zero breast tenderness or high emotions… my period is due to start today (I have been very very regular over the last 5 years with a 26 day cycle, 12 day luteal phase) I have had some weird cramping on my left side since last night that feels kind of like bad ovulation cramping? It hurts to twist certain ways and is tender to the touch but nothing excruciating.

I’ll be taking a test tomorrow morning and I took one 4 days ago at approx 9 DPO and it was negative (I think there was an Evap line or very light positive line a few days later when my husband dug it out of the trash)

Just wondering if anyone had zero symptoms like that before a BFP or have any idea about these different cramps?? TIA!!

Low dose aspirin (150mg) can I start?

Upvotes

Hi, so I've had 2 private scans for reassurance, and I've measured 4&5 days ahead of lmp respectively. Midwife is going based off LMP but that puts me a whole 5 days behind my latest scan. I measured 10w3d and that was a few weeks ago.

I am 12w tomorrow based on the last scan, so should I start taking the low dose aspirin tomorrow, due to the fact the scans have been consistently ahead? Or should I wait till my dating scan? By the time I go for that based on my measurements now, I'll be 12w6d.

Sorry for waffling, I'm basically asking is it okay to start tomorrow or should I wait and go off LMP even tho baby measured ahead both times.

Thank you!

Advice Needed Concerned with my HCG vs HPT results

Upvotes

Hi ladies, cautiously entering this sub and really hoping to stay this time.

Had a vvvvvfl, barely visible at 9dpo, Friday evening, so we assume that as implantation day. Next morning the lines got a hair darker, negative ultra early CB digital but positive regular digital.

Very stagnant progression since then, lines darkened but just barely. Went for betas today (12dpo), they came back at 32. I had an PUL in November 2025 (with similar lines and numbers) so I’m naturally horrified of another experience of that nature and now worrying that if the digital picked up a positive on Sat morning (10dpo) I must’ve had enough hCG to indicate positive.

I’m all over the place trying not to freak out as obviously not much I can do at this point but wait for the second beta, but I was thinking, what are the chances the digital was false ? That’s my only hope that things could still be ok. I appreciate I’m being completely irrational but any support or relevant is expected is welcome, if any of you are willing to share.
