i had my 20 wk ultrasound last week, it was so amazing and everything was perfect (a big relief), however she asked me how far along i was and i said 20 weeks that day, but she said i was measuring 21 weeks and probably ovulated a week earlier than i thought i did. the thing is i had given up ttc at that time and actually have no idea when conception occured so it could've been earlier. she said it's up to my dr whether they bring me forward a week or leave it as is.
so do i count it that i'm 20 or 21 weeks. has anyone else been told this.
thanks
