I am 17w1d with my first. At my last checkup my doctor asked if I would like to take the NIPT to test for downs. Mine came back that my baby has a 1 in 200 chance of having downs. No matter what I am keeping this baby I just want to know for sure to prepare. They have scheduled me to see a specialist for CVS testing and I am just concerned with the chance of miscarriage and any other risks... and tips or advice?
