Oh, I can respond to this too!
With my first pregnancy I was 26 and had a risk of 1:55. I opted for a CVS which wasn't pleasant but I had clear ideas that I needed to know for sure if bubs had downs or not. She didn't which rocked but it was still shocking.
I am on my 2nd pregnancy now and this time the risk was actually way better (1:758 or something) but I opted for the blood test, MSS, at 15 weeks. My result came back at 1:11000 and things are looking good.
If I was you I would opt for the blood test and go from there.
