Hi
I had a CVS at just under 12 weeks ( I'm a carrier for a genetic abnormality so will always have to go through these). I was terrified about how it was going to be but found that the experience itself wasn't too bad at all. The most painful part for me was the first needle that anethetises the area. The collection of DNA was a little uncomfortable but nothing worse than period pains for me personally. I was a little achy afterwards for that day but then felt ok. The major pain is waiting for the results. We were told they would take 2-3 weeks(which was a nightmare anyway) but they had lots of problems detecting the info they needed and we didn't get results until 9 weeks later!!! By which time we had already committed ourselves to the pregnancy. I think it was just because of the complexity of the tests they had to do for our situation but it was really hard waiting.
I'm sure yours will be far more straight forward and you'll be fine!
Hope that helps.
