Due date pushed back?

[j200]

Hi so I had a private scan today at what I thought was 9+5 as I conceived on fertility treatment so pretty sure of day of ovulation, she said I was measuring at 9+1, all looked fine 170 heartbeat and saw movement too but I am really puzzled . I had a scan at 8+1 but this sonographer said then I was measuring 7+5 so my rate of growth is normal..., please reassure me it will be ok- really can't go through losing this baby after the journey getting here....

Your calculated dates work off your last period but that doesn't take into account when conception and implantation actually happened (as these can vary). So the fact that you have had two scans that date you 4 days behind where you think suggests that your due date is actually slightly different to what you thought. Please don't worry, this is v v common.

Thankyou
