Amniocentesis help

Amy
I am looking for help in deciding whether or not I should have an amniocentesis. My sweet baby girl had an abnormal nuchal translucency at 12 weeks. I had an ultrasound with a specialist at 14 weeks and the specialist said the baby has a cystic hygroma and her movements were abnormal. I did have the Harmony test and the results were low risk for everything. So downs syndrome, turners syndrome, and trisomy 13 and 18 have basically been ruled out according to the specialist. I am going back at about 18 weeks for a detailed fetal anatomy scan and from there we will decide if they want to do an amniocentesis. I am just concerned about the risks. No matter what the results, I will not terminate this pregnancy so that would not be a reason to do the amnio. I just want to be prepared for whatever I might have to deal with in regards to my little one. Can anyone share their experiences? How did you decide whether or not to have an amnio, what were the results and how did things go after that? Were there any complications? Did you have issues during pregnancy and the baby ended up being healthy? Or vice versa? Just looking for some guidance...
