Identical vanishing twin??

[Amandabg1983]

I am holding there are others out there who have experienced the same thing.
I went in for my 8 week US and found out we had a vanishing identical twin that had stopped living at 7 weeks. Our thriving twin had a strong heartbeat.

We had our NT scab at 12w3d and the measurements were good (1.1mm), but the bloodwork put me at 1 in 63 risk for Downs. I am 36, so that doesn’t help my risk either.

Our Genetic Counselor gold is that if the vanished twin had chromosomal abnormalities, then so would the living twin since they are identical and thus have the same DNA.

We have a scheduled amnio at 16 weeks, since more bloodwork could have co founded results.

Has anyone else had a vanished IDENTICAL twin and still had the other baby be ok?

Also, I swear I’m not drunk. Apparently my fat fingers can’t type.

Hi! I had the exact same situation. My genetic counselor, MFM or OB didn’t share this concern but I do! When I brought it up they said that my remaining one wouldn’t have developed as well if it was a chromosome abnormality. We had the NIPT test done and this was PGS tested so they weren’t concerned. I’m regretting not getting the amnio now. Let me know how yours turned out!

How did your pregnancy go OP?

I had VTS. Both were growing fine until twin 2 stopped growing at 11 weeks.

Twin 1 is now a healthy (and annoying) almost 6 year old!

I hope all went well for you x
