What do i do?

The best suggestion I have is to use the home ovulation test kits. That way you'll know exactly when you're ovulating. Don't stress too much, stress doesn't help. Have sure your boyfriend wear boxers, if he doesn't already. Eat a healthy diet, start taking prenatal vitamins (I like the GNC prenatal pack), exercise. Don't drink, don't smoke.

Your age will depend on how long a doctor will have you try getting pregnant naturally before referring you to a fertility specialist. If you're in your 20's you should try for a year or two, if you're in your 30's you should try for 6 months to a year, and if you're in your 40's you shold try for up to 6 months. The older you are the more difficulties you'll have, so doctors will intervene sooner.
