Starting Ongoing Contraception after EC Use

Although EC may prevent pregnancy due to recent unprotected intercourse, it does not protect you from pregnancy in the future. Because EC can delay ovulation, you may be at risk of pregnancy in the first few days after treatment. You should use an effective method of birth control until your next menstrual period and thereafter. If you are not currently using a prescription method (e.g., pills, or shots) on a regular basis, or if you are interested in changing your method of contraception, please consult your doctor or ask your pharmacist for a referral to a local provider.
