Ultrasound dated less??

Question

I am sure of my last period date and should have been 8 weeks 2 days. Went for an ultrasound today and doctor said the baby and sac are measuring 6 weeks 2 days. Getting nervous. Any similar stories?? I go back in 2 weeks for repeat ultrasound.

Answer

Did you track your ovulation? Lmp is just a guess based off of ovulating at cycle day 14. But not all women - myself included - ovulate then. If you didn't track and don't know for certain your ovulation date you probably just ovulated late. So long as doc is okay with how baby looks, I'd try not to worry.

Good luck.

Answer

This JUST happened to me this morning! I was more than positive that I was 10 weeks and 2 days but I'm only 8w2d 😐

Answer

You could've ovulated later, was there at least a visible heartbeat? I only ask because I had a scan at 11 weeks and baby was only 9 weeks with no heartbeat a couple years ago.

Answer

That happened to me, it was supposed to be 8 weeks but ended up being 6 weeks 4 days. I ovulated really late in my cycle so I conceived a week and a half later than I thought I did. Going by the first day of my last period wasn't accurate 😊 I got a new due date and go by that!
