Need reassurance

[Bluebellgal8]

Hi all, in need of guidance/reassurance.

Had my anomaly scan today and all good except baby measuring small so I have to be rescanned in 3 weeks (obviously that was hard to hear). Only thing is, I've been wondering since the start whether my dating scan was wrong because I had to ask the sanographer at the end what the new due date was as he didn't tell us. He umm'd and arr'd and then said Boxing Day, which was my original due date.

I was surprised by this because that date was going off first day of last period which was 21st March, but I only had unprotected sex on 8th April so would have been conceived on that date or around that date. So I would have thought the due date would be more like early January. I had a private gender scan as well and they had the estimated due date as New Year's Day going off measurements but they never told me to talk to the hospital about updating the due date or anything, they didn't even mention it actually I only realised that after because it was on the scan pics.

Just wondering if anyone else thinks it's plausible that the sanographer was wrong at the dating scan? Anyone else had anything like this happen? My midwife has also forgotten to weigh and measure me in both of my previous appointments so I just feel a bit deflated and confused by it all really.

I would ask my midwife for advice but she doesn't respond to me..

TIA x

I wouldn’t get too hung up on it, if baby is measuring small they will just keep an eye, baby should still follow a line on the chart, as long as baby doesn’t keep dropping centiles it’s ok.

Midwives don’t weigh you at every appointment, only at your booking appointment to work out your bmi. They won’t start measuring your bump until 28 weeks.

It goes from the date of your last period, not the date you conceived.

If everything else looks okay I wouldn’t worry it’s totally out of your control and the scans aren’t always that accurate in terms of dating / size..:.as others said it’s about the trend.

Thanks guys, that's helped a lot 😊

Pregnancy terms aren't an exact science anyway. Some women go more weeks than they estimate and some less and there have been fully developed and healthy babies born both ways.

My daughter was born "three weeks early" but she was 9 pounds (0.64 stone) and fully developed.
