Are their over the counter male fertility tests out there now? And how long should it take to get pregnant?

I'm 35. I did have an abortion at 17 (which I do regret) because my Mom said it'd be best. Could the abortion have caused me to be infertile? I was on the pill for years but went off of them a couple of years ago. My bf of 8 years pulls out. I've never even had a pregnancy scare. A couple of Drs. told me that I may have endometrosis because I have bad cramps during my period. How can I tell if I'm fertile? Should a gynecologist be able to tell during a regular exam? How can I tell if I'm ovulating? I've also thought my bf may be infertile. He does smoke a lot of pot. He's too embared to go to a doctor for this though and I thought I read of an over the counter test. Where could I find one? If we have every few days and atleast several times a day when I'm ovulating for atleast 6 months, shouldn't I get pregnant? I really am getting worried! I was adopted so it's so important for me to have someone biologically related to me and I finally feel ready to be a Mom!
