So I have a drs appt this week to discuss this more. But last week we were shipped out to a perinatologist because I came back as a carrier for cf as well as my quad screen came back elevated for him possibly having down syndrome. We met with a genetic counselor and had an ultrasound where the dr said she didnt see any physical signs that he has downs. In the mean time my DH got tested to see if he is a carrier and found out yesterday that in fact he is. The perinatiologist doesnt want to do an amnio until 30 weeks. So one of my questions is will the amnio give us a for sure wether he has cf or not? I know he has a 1 in 4 chance. But also if we are both carriers how is there a 25% chance that our son will not be a carrier like how would he not get one of the genes from either of us?
