For healthy women under age 30, the chances of being infertile are extremely slim. In the U.S., fewer than 1 in 100 women under age 30 get medical treatment because they’ve had trouble getting pregnant—getting audited by the IRS is more likely (do you know anybody who’s been audited by the IRS?). Some women may think they are infertile because they’ve had unprotected sex and not gotten pregnant, but the bottom line is that this is usually luck, not infertility. For couples under age 30 who have sex once a week and don’t use birth control, over 95% of them will be pregnant within a year.

I.e., if you think because you’ve had unprotected sex and not gotten pregnant you’re probably infertile and don’t need to use birth control, you should read the rest of this article immediately (and then get on birth control).
