I dont know what to think.

Recently one of my friends just announced that her an her boyfriend are expecting. At first I was happy an now I'm jealous along with sad. Nearly all my close friends an family are having little ones. I'm worried that My boyfriend an I cannot :( It's crushing me. I have yet to conceive . We haven't really been "trying" you can say we are just not using any kind of protection because we know if we try it's not gonna happen when we want it to. What do I think? :(
