I think the first thing you should do is decide if the results really even matter. We have a genetic disease in my family that kills babies before their 2nd birthday, usually much earlier. We discussed our risk factors, etc, with a genetic counselor. The blood tests these other ladies mentioned either weren't available or weren't affordable, but we could have done an amino.
We ultimately decided the results didn't matter. Termination isn't an option for us, so we have researched the disease, symptoms, treatment, etc, so we can be prepared and prolong our baby's quality of life. We couldn't stand the thought of carrying our baby to term knowing as soon as she was born, her clock was ticking.
Just keep in mind that no matter what you do or what the results are, you and your OH will decide the right thing for your family.
