Maybe your not ovulating...
If you are really concern than I suggest that you go to a gynecologist and have them check you out.
Or maybe your not having sex on your fertile days...

Statistics say that 90% of girls that have unprotected sex will become pregnant within a year and in my case, thats true!

But all I can tell you to do is ask your doctor.

Good luck!

Its been 3 years and nothing has happend guess im lucky but I know it can happen

What would not ovualting can't spell mean?

It is also very possible that your boyfriend is sterile or has defective sperm. It is much easier to get him tested than yourself, it would probably be worth doing that so that you can relax, about (a) having unprotected sex (but it it is just a low sperm count, or what they call sperm with poor motility, i.E. They don't swim too well, then you could still get pregnant but it is just less likely), and (b) know that you could get pregnant in future, just maybe not with his sperm.

It could very well be your boyfriend and not you that is infertile.Not always the woman's fault!!You might want to address this issue with a doctor,they can do tests to check hormone levels and see if you are fertile.Good luck.Patty

The boyfriend could be the problem and also i'll admit I was on and off birthcontrol alot with unprotected sex and I didnt get pregnant till now?
