Your doctor will do a dating ultrasound and figure out your due date from there.
How exciting you got a dating ultrasound! Congrats :) I called my hospital to tell my doc the news. I am waiting to be told when I can be scheduled in by the tech. So exciting! I thought for sure with my last period nothing could possibly survive in my uterus lol.
I have the same problem I was on the pill I finished my pack and should have got my period on 10/28 but didn't I know I wasn't prego then lol so I ovulated at some point I went to the Dr yesterday for an ultrasound to find out how far along I am and I'm 6 weeks today. Just call and get an ultrasound .
