Identical or Fraternal

[valbri1986]

10 weeks pregnant had my first doc appt yesterday, so happy to say we are having twins, such a blessing!!

I finally understand why i have been abnormally tired and extra hormonal!

I had my first ultrasound yesterday and my doc didn't tell me if they were identical or fraternal, is it too soon to tell, how can we tell?

The first and easiest is 2 sacs vs. 1 sac and 2 placentas vs 1 placenta. I can not remember how soon I found out mine were fraternal. Only one sac would confirm identical; extremely rare cases of 1 placenta have occured with fraternal twins.

If they are identical and the egg splits before 5 days after conception then they can have two sacs and two placentas. However, in fraternal twins the placentas meet and cause sort of a peak or mountain and they will have 4 membranes between the placentas. If identical they are smooth where they meet and have 2 membranes between them. Our Perinatologist is fairly sure ours are fraternal due to the above information, however if they are born and look very similar then you can have a DNA test to confirm identical or fraternal.
Also if you are over 30 they are more likely fraternal and under 30 more likely identical.
Double Congrats BTW
