I had an amnio, but my sisters in law had the CVS. The one thing I was pissed at my doctors about was that they were more into amnio than CVS, and I would have liked to have results much sooner -which CVS will give you. CVS has become more and more common, but it's still a really good idea to see a specialist who does them all the time. I know several others who have had CVS, and there have been no problems, and everyone I know who has done it saw a specialist.Most practices either have an in-house doctor who does most of their amnios and CVS or they will refer you.
There are some GREAT reasons to have at least one of them done regardless of if you would terminate or not! There are several abnormalities -including spina bifida -that can be greatly helped or completely repaired IN UTERO if they catch them from a CVS or amnio. No, they can't do anything if there's a genetic issue, but saying not to test if you wouldn't terminate is no longer good practice.
I was 36 and 38 with my pregnancies and the testing brought a fabulous sense of relief! My sisters in law and several friends have all had perfectly healthy babies at 42,43 and 44. My own grandmother had my mother at age 43! So, everything is probably just fine -but if it worries you, have the test and have a CVS so you can know sooner than later.
