i was measuring a full week behind.at 5 weeks, 6 weeks and 8 weeks.... but at my 12 week ultrasound i measured exactly 12 weeks, so it caught up , so to say.
I wouldn't worry too much about 4 days. The ultrasound results can vary by 4 days anyway, and you could have ovulated late.
Best of luck. Please keep us posted.
When I went in for my first ultrasound, the baby measured 6 days earlier than it should have been based on LMP. This could have been because I ovulated late, or conceived late in the ovulation cycle. By my next ultrasound, it seemed to have caught up about 4 days. At any rate, I'm almost 12 weeks now and everything seems fine.
Earlier this year I had a miscarriage and at the first ultrasound the fetus measured small for dates.
Maybe that is not any more helpful for you than your doctor's "50/50" odds. Doctors can give the most annoying answers sometimes!!!
Ultimately, I don't think a 4 day variation is unusual. Try not to worry (haha, good luck!). If you read this forum regularly, you'll see that worrying is part of the job description!
I go back wednesday 11/28. Thanks for the positive info
The sac is only measuring 4 days off. My doctor told me there is a week leeway. I would not be too concerned yet. When do you go back?
