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. He already has a kid from a previous relationship 5yrs ago, mind you. 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!
