With my first child, the triple screen came back abnormal and the ultrasound showed cysts around the brain. They also thought the heart was not formed right. We were told that there was a very good chance our daugther had Downs or Trisomy 18. Thankfully, our OB gave us really great advice. He told us that sometimes science is ahead of us and we can't always be sure of what we are finding. He also told us that since there was nothing they could do to change what might be wrong with our daughter, we should consider not having the amnio unless we would terminate the pregnancy. He thought the risks to the baby were not worth it.
When my daughter was born at 32 weeks, they could tell us that she didn't have Downs or Trisomy 18 but the cysts were still present and she would have preemie issues. At six months we were sent for an MRI because of sudden, rapid head growth. Turns out she is just a big headed kid who takes after both her parents. The cysts were still present but the neurologist was not concerned because they were decreasing in size.
Today, she is a healthy, happy eight year old who is a great kid. Her teacher calls her "the total package". She is bright, cute and very kind. I thank God every day for her and tell her all the time that she is my miracle. I don't regret the months of not knowing because I have her with me everyday.
