Am I infertile?

Ive been having unprotected sex for 10 years. Not a single pregnancy scare. No miscarriages. Nothing. My periods are most times on the dot on time. last the 4 days and end on a dime. My husband (19) wants to be a dad above anything else. And Ive been wanting to have a baby since I was 18. Im now 28. He battles often enough to be concerned with ED. He and I have been trying for 6 months. Not even a whisper of hope. Are there boosts. or a test? Im panicking listening to my biological clock.
