Getting pregnant

I wanted to know if anyone has been through something similar to what I've experienced. When I was in my late teens I had two abortions. One was because I freaked out and the other one was because the guy I was with was making threats towards me. Now that I'm with someone that I'm ready to get pregnant seems like I cant. We've been having unprotected sex for a very long time. Would the abortions have something to do with it or could it be something else.
