Call your Dr today: The most commonly used types of emergency postcoital contraception ('morning after pills') like Plan B work best within 3 days after unprotected sex, but may be less effective up to 5 days after. Another type of pill, ella, (ulipristal acetate) is approved for up to 5 days after sex. If you don't have a regular doctor call a planned parenthood clinic. Talk about birth control options too.
