Has anyone had this test and what are the risks? I am torn between having it done and knowing the outcome. I read that it could cause limb deformities in the fetus. My doctor recommends an amnio instead of the CVS. But I can have the CVS at 11 weeks verses the Amnio at 16 weeks. Any help with this would be great. My son has DMD and I am not a carrier and no family history!!
