Yes, we did it too.

On the 16th week, the other gynae (not hospital) was supposed to check the thickness at the back of the neck to see if its down syndrome. He didnt recommend blood test. Obviously just watching the ultrasound was not good enough for us.

We went through what your wife did and got the result like you said. It was a boy but a relief. Yes, the process is dangerous and we signed the papers too.

Thank God everything is OK!
