Baby measuring 6 days behind at 8 week scan.

[mermaidsftw]

I had an early reassurance scan on Saturday after a small bleed a couple of days earlier.

I was supposed to be 8 weeks bang on according to my dates and when I ovulated (I know exactly which day i ovulated) she did an internal scan and found the baby with a strong heartbeat but measuring in a 7+1 as opposed to 8 weeks. I’m trying not to panic but it seems like a lot to me at this stage. I was told the earlier the scans are, the more accurate to the day. There was a strong heartbeat which is a good sign but I’ve seen loads of threads where women have had a strong heartbeat and measured early and still miscarried.

I’m still having symptoms which I suppose is a good thing. They didn’t seem worried at the hospital but they didn’t tell me if they allowed a +/- amount of days for error.

Anyone else had this?

I heard the earlier it is, the more unreliable it is. I had:

A six week scan which said I was at 5 weeks.
A seven week scan which said I was 6w 6d.
A scan at 12+6 which put me at 13+3.

Try not to worry. X

Although you know the day you ovulated, afaik there is no way to know the day you actually conceived as sperm can impregnate up to a week after sex. It is easy to say try not to worry - we all know how hard T1 is for worry - but if the sonographer isn't concerned and the heartbeat is good then you're as well placed as can be at this stage.

My early scan date was still out from my 12 week scan date but all was fine.

I had a scan at 5+6 which they said was only 5+1 and he is fine, 6 years old now and healthy 8lb 15oz at 39+6 when he was born

couldnt read and run.... they grow so different at the super early stage.

ive had 4 babies.

our last one (IVF so we knew to the minute when she was concieved) we were scanned weekly from 6 weeks.... her scans showed way behind, then way in front... its COMPLETELY normal.... theyre really inaccurate at the beginning. your next scan baby may be measuring different again. COMPLETELY AND UTTERLY NORMAL.

ENjoy your pregnancy. & congratulations :-)

I had this, about the same gestation. Told DP that clearly his sperm had been faffing about for the best part of a week! Dd born about 10 days early from that scan calculation, spot on average weight.

I had an early scan at what should of been 7weeks. They said I was 5w. I went back a week later told I was 6w3d. They I had my 12 week nhs scan where I should of been 11w6day they moved my date to 13w1d. In now 33w2d.

The earlier the scan the harder it is to date. A millimeter either way can change dates by days. Xx

They said all the way through my last trimester my baby wasn't growing, measuring dangerously small. He came out over 10 pounds. They get things wrong all the time. It's not a window in to your tummy. A good heart beat is a much better indicator. Try not to worry about it

Wow!! Thank you all! Feeling very reassured. I don’t think I’d have been so panicky of it was under 5 days out.

I’m feeling very reassured now.

I had an early scan at 7w 6d from LMP that dated me at 6w 4d.. went back 2 weeks later expecting to be 8w 5d and was told I was 9w 1d...

I’m guessing that they’re very rarely bang on and in line with each other at each scan then?

I can’t remember if my dates changed after my early scan with DD. I know I wasn’t concerned though.

Congratulations! I had some bleeding in early pregnancy (also had 2 previous MCs) so they scanned me at what I thought was 6 weeks, couldn't see a fetal pole or heartbeat so was asked to return 2 weeks later, I was expecting to be around 8 weeks - turns out I was only 6 weeks and a few days! I was gutted as I felt like I was starting all over again but we saw a heartbeat and I'm now 36 weeks tomorrow So it doesn't always mean bad news!
