Why is it taking so long??

I’ve been trying for 8 months. What can I take or do to help me conceive? I’m only 29. I have gotten checked for everything that I know of, and everything came back fine. I don’t smoke or drink. I take vitamins, I exercise everything. I know I am ovulating but just don’t understand why I haven’t gotten pregnant yet. I quit all BC over a year ago almost 2 years. HELP!!! Please don’t tell me wait a year I have heard it to many times. I’m looking for a solution before I turn 30!
