I had a scan with DD1 and I didn't agree with the date. We ended going with my dates as I was 100% certain when I fell pregnant.
With DD2 I didn't have one as the Dr said he would again go with my dates.
Back then you didn't see much and were told even less. I think you were around 20 weeks before you were offered a scan and you didn't have any pictures to take home.
I don't think it made any difference to how I felt being pregnant :)
