currently prenatal dna testing for paternity involves invasive procedures that carry a risk of miscarriage. these procedures typically aren't performed until at least 10 to 15 weeks' gestation. therefore it's unlikely your ob-gyn would be willing to attempt such testing at only 8 weeks' gestation. prenatal testing for paternity actually is rather rare and reserved for special circumstances. most paternity testing is performed after the baby is born. i would urge you to discuss the issue of prenatal paternity testing with your ob-gyn to get his or her advice on whether or not it would be advisable in your case. all the best to you!
would my obgyn do a dna paternity test at 8 weeks if i asked?
