Trying for our third! help!

We have been trying for almost a year to have our third child! We have a 11 yr and 10 yr old kiddos, but we have been trying for a third baby and it hasn't happened yet. I had a cone biopsy two years ago and not sure if it's because of that and can't get pregnant . I tried Clomid and that did not work. What can I take to get pregnant faster?
