Emergency contraception (or EC) is a kind of birth control you can use after an unprotected sexual encounter. You have up to 5 days after unprotected sex to use EC. EC works to prevent a pregnancy before it starts, and taking EC will not terminate an existing pregnancy. (That means it wonít work if you are already pregnant.) EC also doesnít protect against HIV or other STDs.
You may need EC in the following situations:
- You had sex and ...
- you didnít use anything to prevent pregnancy
- your birth control method failed Ė like your condom broke or slipped off, or your partner didnít pull out in time
- you are late for your Depo shot
- you have missed doses of your birth control pill
- You were forced to have unprotected sex
City Clinic can help you with the following options for EC:
- ella (pill)
- Plan B (pill)
- Paragard (copper, non-hormonal) IUD (intrauterine device)
- Please note: we cannot perform Paragard insertions at this time, but we can help you locate a clinic near you that offers this service.
