Possible identical twins !?!

Hello All.

I had an u/s last Friday (Nov 28) at 6w3d. We saw two yolk sacs and one baby (with a HB) on a rather low tech u/s machine. Since then my m/s has gotten unbearable and I am starting on meds (25mg B6 3x per day and 1/2 Unisom tab at night) and I just had another u/s scheduled as the doctor thinks that 2nd yolk sac might be another baby. Does this happen? I am beyond nervous and a tiny bit excited. Thought you ladies might have some insight. Thanks!

Yes, it is possible that the second yolk sac could show a viable embryo/fetus at some point. I think you are about 7 weeks now, so you should know soon. I do want to say that if it happens to be twins, don't assume they are identical. Many spontaneous twins are fraternal. There won't be much of a way to tell until you know their sexes or you have genetic testing completed after they are born. OR, if you are like me, your possible twins will have different eye and hair colors making it very clear that they are fraternal. Biggrin

I agree. They may not be identical twins. But congrats and kup.

I should have said there were two yolk sacs in the same gestational sac. That does mean identical twins, doesn't it? Most likely mono-di from what I have read, but you guys are the experts. I have an u/s scheduled for this Friday so we'll see. Will let you know. Thanks.

If they are sharing a sac then, yes, they are identical. Congrats Smile My mom is an identical and at 55 they still look a lot alike, talk a like and they even write the same (its so funny) KUP on any developments and welcome to the world of mulitples.

exciting! You should know more soon. KUP!

I saw two "blobs" at a 5.5 wk u/s (bleeding and I panicked on a Sun and went to the er lol). The u/s tech only pointed out the one, but I knew I saw two (the second was more oval than round looking) but a bit later the er doc told me I had twins, but had miscarried one. Apparently she was wrong. lol

Yes, then they are probably identical. Good luck!
