  I'll second that, they have to be identical.

  If they are truly mono/di, they are identical.

  However, two placentas can fuse and look like 1 placenta, giving the illusion of mono/di twins when they really aren't.

   Or if your twins are like mine, they are mono/di but with a ridge in the placenta that tricks the peri into thinking there were 2 fused placentas on ultrasound, and a pathologist confirms that there was only 1 in there.

  That's true. The nurse tried to tell me at delivery that there was just one placenta (and she showed it to me; it did look like one) but on u/s earlier on they had always said they were di/di and they're clearly fraternal so the placentas must have fused.

  They'd have to be identical.

   

  Its one of the reason that they took about 5 different shots of my 2 separate placentas way back at my NT scan. Good thing they did, because now they look like one on the ultrasound.
