I will be having an amnio(m)We lost a baby girl at 18 weeks to a rare chromosone disorder. I did have an amnio with her when they found problems, and I also had one with my next two children.
I use a perinatolgist that spends most of his days doing amnios at a major hospital. It was a tiny bit uncomfortable but certainly not bad in anyway. The wait for results is far worse. I had no problems thankfully after any of them.
Most problems are caused by inexperienced OB's who try and do an amnio unguided by u/s.
There was recently a published study showing that amnios today are nowhere near as risky as the 1 in 200 that they have been reporting. More like 1 in 2800 I recall it saying.
Good Luck, it's not an easy decision for anybody.
