How do you know if your infertile?

Not pregnant...: If you do not become pregnant after 1 year of unprotected sex with a fertile partner, you are considered infertile. Most women, however, would not wait that long before having an evaluation.

Definition: In your age group, 1 year of unprotected intercourse without pregnancy. Also if you have cycles that range longer than 30 days, you are at much higher risk of infertility and higher risk of miscarriage and should seek help now as opposed to waiting a year. Best of luck.
