Hi,

I had my first scan this morning. I thought I was 8.5 weeks pregnant but the doc said it looked more like 7.5 weeks. I saw a heartbeat and everything looked relatively ok but it has worried me that I am only 7.5 weeks because I know that's not possible - I know the exact dates we BD'd on.

I know my query probably sounds silly but I am worrying a little that maybe development is slow. Can anyone offer any advice?

I dont understand either how they work things out, I had my first scan Friday and they put my dates forward i was confused about this as it works out i must have got pregnant staright away after my period and not when i thought i did......

I wouldn't worry about it x

Dont worry when I had my first scan I measured at 7 days less then I KNEW I was, so they pushed my due date back. When I went for my 20 week scan ta da! I measured at the exact dates I knew it was. The US is an estimate only

they did that 2 me 2. i went thinking i was 7.5 and they said i'm 5 or 6 weeks now

Well, basically, in the right conditions sperm can live approximately a week So seeing as you have a heartbeat, things should be just fine. Don't worry

I had my first visit today and they started playing with my dates too... way confusing I can definitely sympathize with you. Fingers are crossed that it's all good

Thanks girls for all your replies, it has made me feel alot better.

I wouldnt worry at all, the same thing happened to me, at my 12 week scan they said the baby was a bit small for my dates, however as we were ttc for a while i had been writing everything down so i knew my dates were accurate.. I was worried, thinking why is the baby small..

But... when I had my 20 week scan the baby is going brilliant and is perfect for my dates..

So all that worry for nothing..

standard deviation for scans is +/- 7 days, so don't even worry about that.
