Not sure what treatment I need yet.

When I was 15 years old I got pregnant. My parents let me make my own choice if I wanted to have it or not. They weren't happy but I had an abortion. Ever since then I haven't been able to get pregnant. I'm now 25 years old, with a cycle that runs like clockwork. I was married for 4 years and didn't get pregnant. I'm not sure if he was infertility or not. Now I have been with my boyfriend for almost 2 years and still haven't got pregnant. I know he is fertility because he already has kids with his ex-wife. I haven't been to the doctor yet about it because I'm a little scared or what they might say. Also not sure on how much money it will be just to find out. I have been doing my research online and I think it might be pcos because I do have some facial hair.
