I'm afraid I cant have kids

I had cervicitis a couple years ago. And the doctor told me there is a possibility I won't be able to have kids. I've been trying a year now and still not pregnant. Is there a way i can be more fertile in a way. The problem is I'm not regular on my period I'm really scared that I actually can't get pregnant. Please do not suggest adopt because that's way too hard with my profession since I'm not rich.
