I just ended my period. My boyfriend came and then an hour and a half later he we did it wihtout a condom… Could i be pregnant?

It’s possible. A woman is most likely to get pregnant if she has unprotected sex anytime during the six days that end in ovulation, when her body releases an egg. This is because sperm can live in your body for up to six days. That means that even if you weren’t ovulating when you had sex, it’s still possible that the sperm and egg joined later on.

Women ovulate between 14 and 16 days before their period begins. Women with short cycles (21-22 days or so) are at high risk of unintended pregnancy if they have unprotected sex during their periods. Because young women often have irregular periods, it is very important that they always use protection whenever they have vaginal intercourse.

The morning-after pill (also known as emergency contraception) is a safe and effective way to reduce the risk of pregnancy after unprotected intercourse. It can be started up to five days (120 hours) after unprotected sex. The brands Plan B One-Step and Next Choice are available from drugstores and health centers without a prescription for women and men 17 and older. A new brand, ella, is available by prescription only. If you are interested in getting emergency contraception and you’re 17 or older, you can get it either from a Planned Parenthood health center or from your local drugstore. If you are younger than 17, you’ll need to go to a health center or private health care provider for a prescription.

The best way to prevent pregnancy is to not have sex or to use birth control if you do have sex. Learn more about your birth control options.
