This had to be a huge shock - it's amazing that they did not pick this up before 9.5 weeks. I can imagine it must be a huge adjustment to first learn that you are carrying twins and then to find out they are monoamniotic. I do not have personal experience with a monoamniotic or even a twin pregnancy but through my work, I know of 6 women who had monoamniotic pregnancies - of the six, two had healthy twins and one had one healthy baby. It is a very high risk situation, as you know, but there are success stories out there - so keep all thoughts positive. I wish you and those little beans all the luck in the world - keep us posted.
You should look up Jennlaurin80 you can also see her on my friend list.
She is pregnant now with identical twins. She is 19 weeks.
Best wishes to you.
I had personal experience but prefer not to hold it up as an example because it was sad. I hope you do well with this pregnancy, and have a happy and uneventful nine months.
