I have reserves about it because I am scared of Down's Syndrome but this is my second marriage and I have two boys from the first that are 19 and 13. My husband does not have any kids of his own and we would like to have one. I had a tubal ligation and we are getting my tubal reversed so we can get pregnant but my question is what is CVS? I know what Amniocentesis is but I have never heard of CVS. Can someone explain to me. We want so much to conceive so I was wondering how many women can after 40.View Thread
