Does anyone have any experience with measuring behind at dating scans? It has been 9 months since our 22w loss and we were finally blessed with another pregnancy. I had my scan last week at 7+5 and I was measured at 6+1. The tech said she only saw a sac but I later learned from the radiology report that there was a yolk sac and fetal pole as well but no heartbeat detected. I know when we conceived because we only DTD once in the window and I chart and use OPKs. I got my BFP at 10dpo but basically my new dates say I got the BFP the day I conceived. I'm not feeling very positive about things but maybe someone out there has been in a similar situation with a good outcome?

So...I may have my dates somewhat off here but the spread is right.
Conceived cd14 (know the date exactly because we dtd that weekend and thats it bc I was traveling a ton that month for work!).
Dating u/s at 6+1 and was measuring 5+1...I was livid they moved my due date. They moved my due date from 8/28 (based on both O and LMP) to 9/3 based on dating u/s.
I was convinced they were wrong. I delivered on 9/5.
Not much to offer other than an off dating u/s when I was sure of the date of conception which resulted in a healthy baby!

My daughter measured about 5 days behind at our first ultrasound. She made up the difference by 20 weeks. It is possible that you ovulated a a few days later than you think and got an early bfp, making the difference smaller than you think. Even opks aren't perfect at telling when you ovulated. Fingers crossed for you!!

@delight: I've never measured behind but fingers crossed your next Ultrasound shows heartbeat.
-
I measured nearly a week off, even though I'd been charting. The doctor's explanation was that implantation can take time and that an egg can live for 24+ hours after ovulation. My LO is 2.5 now.
Hoping for the best

I was certain my due date this time would be April 30 and they gave me May 3 based on measurements. Luckily, I was far enough along to see a heartbeat at that ultrasound. Hoping you see a heartbeat soon. I'm sorry you are dealing with this.
-
@delight: Hoping and praying for a good outcome! What day is your follow-up ultrasound?
-
@Autumnmama79: Thursday. Hoping for a heartbeat!
Thanks ladies I appreciate your stories and support.
-
@catlady: That's surprising. I measured 4 days ahead and doctor did not change my due date (he goes by LMP, I wasn't charting/OPK or anything). My OB said they only change if its a week different.
-
Fingers crossed for good news at your next US.
-
@BandDmommy: Based on my LMP date, I was actually "behind" by about 2 weeks. So maybe that's why they changed mine. My ultrasound was specifically for dating purposes since my cycles are very long and irregular. I was basing my own date off my opk.
-
I think by 7W5D you should definitely be able to see the heartbeat so I am hoping that your dates are just off somehow. Late implantation or long lasting sperm with a late ovulation... It happens!
-
I measured behind by a week at 6-7 weeks with both pregnancies. But I did see the heartbeat at that point. Crossing my fingers hard for you!!
-
@sometimesshesings: thanks for the positive stories. I am worried there was no heartbeat. However, the tech didn't see the baby at all so she want trying to measure a heartbeat. The radiologist found the fetal pole when he looked everything over. So maybe there was a heartbeat but the tech didn't know where to look. At least that's one thing I tell myself to keep the hope alive!
-
@travellingbee: thanks for the well wishes. I do hope there are a number of factors like you mentioned that are all playing a role in throwing my dates off. Only two more days and I'll have answers.
-
@delight: that's definitely possible. I seem to remember the doctor needing to zone in on the heart to see it that early.
-
How long was your cycle?
They always measured me a week off for DD2. I had a 35 day cycle the month we conceived, but the standard start for the dating was still using a 28 day cycle, so it looked like I wasn't as far along as I should be.

Cross posted from due date board:
Well I got quite a shock today when the tech found the baby and heartbeat at my follow-up scan. I have no details about what the baby is measuring because the radiologist needs to look everything over and send a report to my doctor. However, the tech showed me the screen and I saw a tiny tiny blob and heartbeat so hopefully things are progressing on the right track. It looks like it is still measuring behind but I'll hold on to some faith for now. I hope I continue to have positive updates. It's Thanksgivong weekend here and I'm definitely thankful for a baby with a heartbeat. Happy Thanksgiving all you fellow Canuck mamas. And thank you everyone for your positive thoughts and prayed during this stressful week.

Yay! Great news!!
-
@delight: that is wonderful. Such a good thing to be thankful for!
-
That's great news!
LO measured 8 days behind at my first scan (I believe 7ish weeks). I knew for sure when she was conceived, and actually argued with the doc a bit about due dates. She continued to measure behind at every scan, generally 1-2 weeks (I had regular scans due to an unrelated medical issue). She was born at 6lbs 2oz,and is 11 months old now and in the 5th percentile for height and weight - turns out she's just a small kid!
Fingers crossed for you!
-
Such wonderful news! I've been hoping for a positive update and I'm so happy for you and your family!!!

@delight: That's great news!
I found out that my LO was measuring a little over a week behind during my NT scan at what I thought was 12 weeks. (I never had a dating scan) It was a little annoying to have to go back a week in my pregnancy. I feel like I have been marking off the weeks as little badges of honor, and to have to go back was pretty annoying. But my Dr found the heartbeat pretty quickly at my next appointment, and I just found the HB with a home doppler, so things must be progressing.
I'm pretty sure of my dates within about 4 or 5 days, so I doubt a late ovulation really has anything to do with it. I'm looking forward to my next US at 20 weeks to see where I am, and I'm trying not to freak out about being a week late.
GL to you! -
yay for heart beats!
I measured 5 days behind at our first ultra sound. Now baby measures big.
Good luck and happy Thanksgiving!! -
@delight: amazing!! Continuing prayers for you and your little tiny gummy bear!
-
Great news! I just saw this post now but I wanted to say I was sure of my dates but measured a week behind at all my ultrasounds and my son is 7 months old and perfectly healthy. Wishing you a happy and healthy pregnancy!
