Amnio And Past Miscarriage Increased Risk

Hi All, I'm supposed to go in for my amniocentesis tomorrow. Looking around on the internet I found a study that says that women with bleeding in current pregnancy suffered fetal loss 6.5% of the time compared to 2.8% regular control group and that women with a history of miscarriages/terminations suffered fetal loss 8% vs.2.8%. Any women have similar experiences? Positive or negative?

I am sure that most pregnancies go on fine but there is a sad story of s.o. on the Third Trimester board who had amnio at 18 weeks and 3 weeks later at her 21 week check-up was told that there was no more amniotic fluid left. Her baby is still alive (32 weeks or so) but about a month behind in growth with little chance of her lungs maturing like they should. It's heartbreaking. Now, I'm sure this is not the case for most women but it is hard to read. Why are you going for the amnio? Is it because of your age or 'bad' blood results? I think it was the latter with the woman in question. The study you mentioned sounds interesting, I hadn't heard about that. You mean women with bleeding who opt for amnio have a higher rate of m/c, am I reading you right?

The article concludes "Bleeding in the current pregnancy, a history of three or more first trimester abortions/miscarriages seem to be significant predisposing factors for fetal loss after an amniocentesis" We had decided from the beginning that we would have the amnio so I didn't even do the other test, particularly because with all of the false negatives/positives, only statistically indicator they didn't seem like they were really going to tell us anything any way...but if the chances of losing it increase so dramatically I don't think it's worth the risk. I don't know I'm really torn.

We also opted for amnio rather than deal w/ the questions surrounding other tests. I didn't have any bleeding during my pregnancy, but was still pretty freaked out by the risk involved. Aside from having to be stuck twice (baby moved toward needle) and mild cramping that day (that's normal), everything was fine. If you do go thru with it, my only advice is do NOT do any physical exercise the rest of day and take it easy the following day. I definitely felt more crampy walking around , so when they take it easy, heed their advice.

Hi again. Do your chances at having a Downs S. baby outweigh the risks of amnio? I think the risk of m/c due to amnio is around 1:250 but it depends on the doctor/clinic too. Did your gyno give you the % risk of Downs for your age? It might be worth comparing and then taking the study you read into account. Did you m/c several times before? Personally I couldn't do it, I would rely very much on the 12 week scan which 'catches' around 75 or 77% of all Downs babies and then further scans later on. I wouldn't opt for blood tests because of false postives. But someone I know did, and she ended up with her chances being 10 times lower or so after combining the scan and blood test results. Her chances of downs had been reduced so dramatically, she didn't opt for amnio any longer because the risk of that was now far higher than her risk of carrying a Downs child. Still, only you (and partner) can make that decision. I hope it all works out for you.
