Dividing membrane?

Brittany

Hello ladies!

Husband and I found out last week that we are pregnant with twins - yayy! We are beyond thrilled. However, the OB said they could not detect a dividing membrane yet, so it's possible that they are Mo/Mo twins. Our original estimate was at 8W2D, however the measurment was at 7W2D - the discrepancy could also be due to twins typically being smaller anyway. Luckily, both heartbeats were strong & healthy, and they were the same size.

My question is : do you think it was just too early to see the two sacs?
