I feel for you. I have had a similar pregnancy with many bumps in the road. I had a subchorionic hematoma early on with tons of bleeding for weeks and was on bed rest then had high AFP levels and there was a spina bifida scare and after all that at my 20 week scan (2 weeks after the early anatomy scan where they looked at everything and told us everything was perfect and this was just a followup) they found a severe congenital heart defect and the most severe variant of it. Because of the condition and the variant there was a 1:3 chance that she could have a genetic disorder that would only give her a 2% chance of living past the age of 1 combined with the severity of the heart defect and if she did she would have mental ******ation and mental illness but no one can say to what degree.
Unfortunately there were no non invasive tests for this disorder so I had to have the amnio. I had a very comprehensive microarray done with my amnio so they can test for many more conditions, microdeletions etc.
The stats at my hospital and of the doctor performing the amnio were great. The doctor has done hundreds of them, never had a loss, never hit a baby with the needle and was incredibly skilled.
The procedure hurt me probably more than most because I think he hit a nerve. The baby was in a breech position, it was just after 20 weeks so a bit late and I have an anterior placenta so he had to work around a lot of obstacles. The procedure was over pretty quickly but at the time I felt like it took forever. They put me in a private room with my husband to lie down and relax for a half hour and gave me juice and cookies after and told me not to get up until I felt up to it.
I was put on bed rest for a couple of days, complete pelvic rest and no lifting for a week and I got the preliminary results in 2 days and the full microarray results over a period of 3 weeks. Every time they got new results in they called to tell me everything was fine but it came in bits and pieces.
At the end of the day as far as anyone can tell she "only" has the heart condition to deal with and we've got a long NICU stay at the hospital when I give birth as well as several more open heart surgeries throughout her life but we are doing the best we can for her and know that our little girl is gonna be a fighter.
Good luck hun! I hope it works out for the best! Hugs!!!!!
