Hi fire,
So sorry to hear your news. It's the most awful shock and something which is so hard to get your head around.
Please feel free to come join us on the 'termination for medical reasons' thread and get some support there.
I terminated my first pregnancy last Thursday at 17+6 after 5 agonising weeks (placenta in wrong place for CVS, amnio rapid results came back clear nd we were told everything would probably be fine, then full results showed an extremely rare deletion). I called ARC and got some really great advice and support from them so second that.
I don't really know what to say or how to help, but there are others going through this and I do know exactly how you feel. If it's any help, this last week has been unbelievably tough but I so far I don't regret my decision.
There are also some wonderful ladies on here who have the benefit of a little time since they went through all this and hearing their experiences really help.
My heart goes out to you and I hope you can make a decision you're comfortable with. Do you have support from your dh and family? Another thing that comforted me was speaking to the genetic councellor about what most other people do in my situation, it made me feel more 'normal'. Having said that, if you search through on here you can find people who kept their babies after a t21 diagnosis and are very happy.
Sorry, bit of a rant and not sure I helped much. Fingers crossed for you that you find a decision you're at peace with. Come talk to us if you do decide to terminate and have any questions or want to rant.
Piz
