Why can’t I get pregnant?


So me and my fiancé have been together for two years. And we’ve been trying for a baby for awhile. Since the beginning, it’s been unprotected. If it happened, it happened. But now, I’m practically begging for one. But NOTHING. I’m scared to go to the doctor for all positive and negative reasons. Either I can’t have babies, or I can but nothing is sticking and I have to just ‘keep trying.’ What do I do?

I’ve had my fair share of drugs but that life is far behind me and I occasionally drink. Help!
