Is it a thin membrane separating them or is it larger? And it could be two placentas that fuse together. I have 1 placenta with a very thin membrane separating mine so they are identical or mo/di. But then again you can have identicals with two separate sacs and 2 placentas. Sometimes you can't tell til they are born or even getting a dna test.
I just posted something about this. Ours were in their own sacs so we were told they were fraternal but turns out the egg split very early and a DNA test confirmed they were identical! I figured they were because they looked so much alike.
