AIBU to think there is something seriously wrong with my baby?

18 replies

Scandiscrepancy · 30/10/2022 01:42

I recently had a dating scan at which point I was 7 weeks 4 days based on the first day of my last period. The fetus only measured 5 weeks 5 days with a heart rate of 93bpm. I am certain of the date of my period and got a positive ovulation test on the 16th day of my cycle so I know I didn’t ovulate late either.
My GP is being irritatingly positive. She seems to think I have my dates wrong but I know I don’t. I was ttc and I always keep track of my period. AIBU to think that there’s no way this baby can be developing normally if my scan date is 13 days out? I’ve had a little nausea but no vomiting and I feel tired but not shattered. By the time I was 6.5 weeks with my previous pregnancy I couldn’t stop vomiting.

Sadly I have had this feeling too and I was right. I had a dating scan at 7 weeks 4 days. Baby measured correctly but had a HR of 90 something. I knew it wasn't right. I went to my 12 week scan and baby died at 7 weeks 4 days. I had my private scan in the morning and I do believe I'd have found out earlier if I had my scan in the afternoon. I still had all the sickness (HG hospital stays) as the sack kept growing but I really did know deep down it wasn't right.
Sorry if this is your outcome too x

OP as difficult as it is you really just need to wait and see.

I wouldn’t read too much into the nausea though, lots of people I know have had very different amounts of sickness with different pregnancies

My pregnancy this time was 15 days out at early scans, my 12 week scan had to be pushed back by 2 weeks as they couldn't do the measurements and then the gap was shortened to 11 days. I'm now overdue.

So it can happen, I have regular cycles and had a positive test the day my period was due, and know when I conceived, so I must have just randomly ovulated later than usual or something.

But I've also had it where I've been more than a week out and it was a MC, and I don't have experience with a low heart rate unfortunately.

I hope it's good news for you

Opks are not hugely reliable. You may be out you never know. Give it a week and get another scan.

Hornicorn · 30/10/2022 04:24

I had something similar and unfortunately it didn’t end well for me. I had a viability scan at about 8 weeks. The sonographer could see a heartbeat but said the baby was measuring at about 6 weeks. I knew my dates couldn’t be two weeks wrong (it would have meant I would have conceived around the day I had my positive test so I knew it was impossible).

I had a scan at the same time with my previous pregnancy and my daughter measured 4 times the size of this baby at the same time (something like 2cm compared to 0.5cm). I queried the size with the sonographer but they said that the pregnancy was viable because of the visible heartbeat and just repeated that my dates must be wrong.

Unfortunately I started to miscarry a few days after and a further scan later showed there was no longer a heartbeat.

I really hope it works out for you and that your outcome is not the same as mine x

I can't comment in regs to heartbeat as I was told they couldn't check how fast it was beating that early at my scan, but I had a scan at 7+4 and was told I was only just measuring 5 weeks. I was very sure of my dates, and I'd only had sex once since a previous miscarriage so I knew I couldn't be only just 5 weeks. They said everything looked fine just earlier than I thought so I must have my dates wrong but I was expecting the worst to be honest. My 12 week scan finally came around at what should of been exactly 12 weeks following my new dates changed from the early scan and I was measuring 14 weeks and 4 days and had caught up. I asked how that could of happened and my midwife said these early scans the margin for error is decimals of a mm it is very easy for them to be out. Got everything crossed for you.

pinkbag · 30/10/2022 05:31

I had something similar about 5 years ago.

unfortunately I miscarried. The wait to find out if the baby had grown was awful.

KingJulien · 30/10/2022 05:35

At this point it is too early for an accurate scan. I’ve had early scans out by that much (but the other way, measuring later) but when you zoom in on the picture, you can see the the measurement line going beyond the sac/fetus.

eachtigertires · 30/10/2022 05:39

My first pregnancy they gave me a gestational age based on the scan which if I had conceived on that week wouldn’t have been possible as DH and I were in different cities that week. But here she is a healthy 2 year old. Wishing you the best of luck OP.

DozyFox · 30/10/2022 05:48

I've known people in your situation who've ended up miscarrying, yes.

I also know a lady who was measuring very small at 6 weeks with a very weak heartbeat. She'd had lots of miscarriages before so prepared for the worst, but she's currently going into her third trimester and everything has been totally fine since.

Unfortunately I think there really is no way to know except wait - your GP was probably being positive because they think you just need to wait and see too and was hoping to make you feel better in the mean time (but it definitely would have wound me up and made me feel dismissed too, so I get it!).

Fingers crossed for you ❤️

lifeinthehills · 30/10/2022 06:21

I've had one more than two weeks out. He's now a strapping 21 year old young man. Unfortunately at your stage of pregnancy you never know what might happen, regardless of dates, so that's no reassurance. Can you do a HCG test? I had mine done with my first and they were increasing at the expected rate, which is reassuring.

Unicorse · 30/10/2022 06:39

It's a horrible limbo to be in. I have had this twice, I'm currently having a miscarriage at 9 weeks after measuring a week behind at a 7 week scan. The sonographer wasn't too worried at my first scan but a follow up scan a week later showed the baby hadn't grown much and although they had a heartbeat it wasn't quite fast enough to be definite proof of viability. I started bleeding a few days ago and had a final scan to confirm the heartbeat had stopped and I am miscarrying.

I have had the opposite experience with my daughter, she measured 6.5 weeks at an 8 week scan even though I knew my dates. My due date was altered and although she stayed small she was absolutely fine and progressed as expected throughout my pregnancy.

I was sure of my dates with both pregnancies as I tracked ovulation through BBT so really can't explain why my daughter's date was behind.

I think it's just one of those things that could go either way and all you can do is wait even though it's horrible and full of anxiety. I really hope you get good news and your baby is just taking their time to grow.

Thank you for all your supportive messages. I had a follow up scan a week later that showed minimal growth and a fetal heart rate of 70 beats per minute. Technically not yet a miscarriage but also not viable. I have been referred to the hospital for treatment of a missed miscarriage as GP seems to think my body should have spontaneously aborted the pregnancy by now.
