Sorry want to butt in here when clearly I have zero experience in this regard.
I have never had an amnio and my first batch of tests came back with minuscule risks, so this is not something have had to really think long and hard about.
However as anyone who has been pregnant we all sit and think "what if."
My first pregnancy was one where I was in a high stress situation, as I had experienced a batch of procedures that a pregnant person should not have undergone, and taken medication a pregnant person should not have undergone and and .... so each scan for us was terrifying as we were sure we were going to see things on the scan that we really did not want to see.
However I used Kingsbury Fetal Assessment Centre and used Dr. Shannon Morris there who continues to amaze me with her experience, and her ability to assess a situation and offer insight and advise/guidance.
When I went in for my scan with my 3rd child (she had been the same doctor for baby 1 and 2) - I was a bit terrified as I was over 35, and 35 had been my mental cut off age - as I felt that on your 35th birthday it was all pretty much downhill from there on in.
Any the who, before she did the blood work and the initial scan we spoke about the "what ifs" and the "maybe's" which are important. She spoke about the risks of an amnio or a CVC and also using the right person to do it, if we chose this as a course of action.
The point I am trying to make - is that even though the risks are small for a M/C - this is one of those procedures, where you grill - literally grill - your doctor as to how many procedures they do a day, and their stats, and then select the best possible person for the task, rather than who ever is available.
My feeling is that if I was faced with an amnio or a CVC I would ensure I was getting a specialist who had degrees up to the ying-yang, and not just someone who did it 2 or 3 times a month.
We can do another thread about men, and the sh*t they bring! Let's save that for another day.
