I am only 18 years old, and have had men that ive been with ejaculate inside me before. once was not on BC, and the other times were on BC. in fact, i started bleeding the 1st time my new man shot in me, as well as the 2nd. the only person in my family who is sterile is my great aunt, however i am concerned that i may be too.i want to take a sterility test, but don't know where to go. my gynecologist?

they are called fertility tests, and you can now buy them at walmart or any drug store. first response makes them. and also, if you are truly concerned, it wouldn't hurt to make an apointment with your gyno.

I do not know why you think you are infertile? If you have sex while on the pill you are not going to get pregant. You said u only had 1 encounter that was not protected... If you do not have timed intercourse when you are ovulating then you are not going to get pregnant. Also even with timed intercourse there is only a 20-25% chance of pregnancy each month.

Fertility testing is done through your doctor.
