I had my 12 week scan last Friday and yesterday I got a call from the hospital to says there's a 1:40 chance of the baby having Down's Syndrome. I'm 13 weeks but I've decided to wait until I can have a amnio. I could have a CVS next week but the risk of miscarraige is so much higher and I would feel so bad if the results came back fine, but I lost the baby as a result. Does anyone know how long it takes to get the results back from an amnio? I left a message with the screeing midwife yesterday but she hasn't rung me back. It's all been a bit of a shock.
