sac small /miscarriage?

had u/s today. Sac measured 5wks2days. I should be 5wks 6days. This same thing happened with my daughter and i had a healthy birth. What is the probabilty of a miscarriage. Dr said 50/50 chance of miscarriage.

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?

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 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.
