Jumping in from the July DDC (although I have gotten 2 due dates, one in late june and one in early july!). I opted to have the CVS after a "grossly abnormal" nuchal scan. I was told the baby may well not be viable and that I could consider terminating based on the nuchal scan alone
. Of course I couldn't do anything like that without knowing what's going on definitively, so I opted for the CVS. I had it last thursday and it didn't hurt much, and I had no bleeding, but I did have cramping for about 6-8 hours. I used the opportunity to stay in bed for 24-48 hours and make my hubby take care of the kids
Based on the nuchal measurements the baby is at huge risk not just for down sydrome but for the other, usually lethal trisomies, so termination is something I would consider for those.
I am just waiting for the results now, I'm pretty depressed as the odds they gave me were not optimistic at all.
I think if you care enough to know if your baby has a trisomy or the other syndromes they test for, and would consider termination based on them, it might be better just to go ahead and get the CVS and skip the nuchal. Because getting the nuchal first will just drag out the process by a week or more, and while the nuchal scan will pick up 80% of trisomies it will also pick up a bunch of women whose babies actually have no problem (though my measurement was so severe that I have very little chance of things being ok, statistically, at least). In other words out of the women they pick up with abnormal readings, only 15% will actually have problems (unless the readings are extreme, like mine, then the odds get much worse). Whereas with a CVS you get a 99% accurate answer and know exactly what you're dealing with.
Mine was done through the cervix and the pain was not bad, and the procedure was over in about 5 minutes (though I wasn't timing it). And while the test has a 1-2% chance of miscarriage you have to remember that, since these are done early in pregnancy, it is likely that some of the miscarriages would have happened anyway, especially in the fetuses that were abnormal.
