Anytime you have unprotected intercourse, there is the risk of pregnancy. The more frequently you have unprotected sex, the more likely it is that you will become pregnant.
Plan B helps prevent pregnancy by delaying ovulation. It is about 75 to 80% effective at preventing pregnancy when taken within 24 hours after unprotected sex. The longer you wait to take it, the less effective it becomes.
Plan B is only effective for one act of intercourse. It is not effective for multiple acts of intercourse performed on multiple days. It does not provide any long term birth control.
In the meantime, if you are not planning a pregnancy, do not have unprotected intercourse. Use condoms or abstain from sex until your next period comes. If your next period is more than 1 week late, do a pregnancy test.
If your test is negative, consider starting a long term method of birth control like birth control pills, patch, vaginal ring or the DepoProvera injection. Family Planning Plus clinics offer birth control for little to no cost, depending on household size and income.
