This is my second set of twins in a row.. In this ultrasound on Tuesday I was 8w2d. Baby A measuring 7w5d, baby B measuring 7w0d. My concern is & I'm wondering how many other women went through this.. At my 6 week ultrasound I saw two yolk sacs which I have read almost always means 2 placentas/ 2 sacs.. But my doc is sending me to a specialist tomorrow bc he is unsure if there is a membrane seperating my babies.. Which would make me even more high risk on top of me already being so & it means identical twins.. My first set were fraternal which is a trait passed down on my side. Identical I read is just a mistake during cell division that is not inherited so I really don't think it's identical after my first set.. Any other women have this issue come up but it turned out fraternal???
