I just wanted to share with you the story about the CVS I had done, so you can be fully aware of the consequences of the procedure. Like the earlier posts said, they generally do the CVS between 10 and 12 weeks. The doctor who performed the CVS on me was a reputable physician, who had done thousands and thousands of these. To make a long story short, we ended up miscarrying our daughter, Rylie, when I was 19 weeks pregnant. They figure I ended up getting an infection from the CVS procedure. The infection spread to the placenta, which then eventually came detached, causing me to miscarry. The only reason I know this is because they sent the placenta in for testing after I delivered Rylie . I am not trying to scare you by sharing my story, but I wanted to make you aware of what could possibly happen. I know the percentage of miscarrying from a CVS is like 1%, but it does happen. At the time I was pregnant, my husband and I wanted to know whether or not the baby had CF before she arrived so we could emotionally prepare ourselves for possibly having a 2nd child with CF. I have regreted that decision each day since we lost Rylie, but at that time in my life that is what I felt I needed to do. So, don't let anyone tell you what to do regarding whether or not to have the CVS done or not. You need to make the decision for yourself. You will be in my thoughts.
