Emergency Contraception

About emergency contraception (EC)

Emergency contraception (EC) is birth control used after unprotected sex (or after contraception failure during sex) to help prevent pregnancy.

EC stops a pregnancy before it happens, either by temporarily stopping ovulation (the release of an egg that can be fertilized by sperm), or by changing the environment of the uterus or cervix so that sperm and egg do not meet. (EC is different from abortion pills, which end a pregnancy that has already begun.)

EC must be taken within 3-5 days of unprotected sex to be effective – but the sooner EC is taken, the better it works to prevent pregnancy.

Which EC option is right for you?

It is important to carefully review the information below to make sure you’re choosing the best option for you. Some EC options may be less effective based on when you had unprotected sex and your BMI.

If prescription EC is the best option for you, please know that we prioritize same-day EC prescriptions whenever possible.
