I am from the October board. Like so many others have said, it is really a very personal decision as to whether to proceed with the amnio or not. Would the outcome make a difference to you? Would you feel better knowing whether if your child has downs or not, so you can better prepare yourself for his/her arrival?
Unlike most, I didn't have any prenatal testing and only had an amnio. For the very reason that the prenatal testing just gives a risk assessment and not a concrete result, like you get from the amnio. The risk of miscarriage with an amnio is incredibly low (especially if done in week 17 or 18, according to my doctor), and lower than the CVS test that is also sometimes recommended.
The anticipation of the test is so much worse than the test itself, which after going through IVF, is almost like getting another shot, with a bit of pressure when the doctor removes the fluid. It takes about 15 minutes in total. Thirty minutes after the test, the doctor did an ultrasound and the baby was fine. The next day, my ob/gyn did a follow-up ultrasound to check the healing of the puncture point (which should seal itself within 8 hours after the test) and check on the baby. All was fine, no bruising, no blood. I then had to take it easy for 5 days -- no lifting, no exercising - just relaxing to make sure everything healed nicely. When I went for my regular appointment last week, all was healed and everything was fine.
We are waiting for the results, which we should get this week.
I'm not advocating amnio one way or the other, but having the test did give me, personally, peace of mind.
The decision in the end is yours and yours alone. I wish you all the best. If you have any other questions, feel free to write to me.
