Amniocentesis is one. There's a new test they're doing now that has less chance of miscarrying (amniocentesis carries of risk of m/c just by performing the test since they insert a needle into your abdominal and into the amniotic sac). I think they test cervical mucous with this new test. I'm not sure. You should ask your doctor.
You'll probably have a few ultrasounds throughout your pregnancy. While it is possible that abnormal sperm can reach the egg, it makes more sense that a stronger sperm would make it and take the pot of gold, if you know what I'm saying. Don't worry yourself until you know what's going on. Hopefully the only worrying you have to do is about swollen ankles and decorating the nursery! Congratulations!!!
do a google search on "in vitro diagnostics" or go somewhere like pregnancy.com they have info on the different tests and when they can be done.
also try googling for "pregnancy testing" , "fetal testing" etc.
when is your first u/s in a week or two they should see a heart beat that is a very good sign but as we have said chances are it was a good spearm
No, I haven't heard anything. I read on a site that abnormal sperm can empregnate you if there are fertile though so that is what worries me.
I honestly don't think you have to worry about the abnormal sperm. They usually won't reach the egg because they can't swim very well; so if you're pregnant, the egg was probably fertilized by a "good" sperm. Good luck to you and congratulations!
no idea but now that you are pregnant i would say it was a healthy spearm that got there good luck did the docs give you any idea what to expect
