Cival,

To be honest I found the hardest thing about having an amnio was making the decision. My Dr suggested it as I am a older mum. It is scary and does carry some risk all of which I'm sure you have been made aware of.
I was able to find a Dr that has done a huge number of them and his stats on things going wrong was really low which made it a bit easier. All I had afterwards was some cramping like AF was due that lasted for about 2 hours and that was it.
Good luck.
