I hope I'm in the right topic...

I have been trying to get pregnant for 4 almost 5 months and nothing yet... I am worried that maybe I can't get pregnant... but I don't really no what to do.
I am wondering if there is anything I can try to help me get pregnant and if that doesn't work how can I find out for sure if I am able?

The only way to find out for sure if you are able is to make an appointment with your GYN. However, most women take 6 - 9 months to get pregnant and lots of doctors won't even see you for fertility issues until you've been trying for at least 1 year.

Its hard but be patient... at this point you have nothing to worry about. Just relax and try to enjoy trying. :)
