Off BC, can't get pregnant

I was on birth control for 10 years and now my husband and I are TTC and have been for 6 months. I went off BC 4 months prior to TTC and still haven't gotten pregnant. I know that's not long to have been trying but I'm getting really frustrated. My periods have been normal since I stopped taking BC and I haven't any problems. Blood work has been fine. I just don't know what else to do. I'm tired of hearing it will happen when it's supposed to happen. Any advice?
