PCOS Infertility

Anyone have PCOS and had children? I can't seem to get pregnant. My boyfriend has been finishing inside of me about once a week for a year and a half and I still haven't gotten pregnant. What can I do to become pregnant without going to the doctor? I'm only 19 so they won't help me out. They just keep trying to push birth control on me. I really want a child though and I'm ready for one.
