Emergency Contraception: FAQs

How do ECs work?

This information is from the U.S. Department of Health and Human Services EC site:

Emergency contraception can keep you from becoming pregnant by:

• Keeping the egg from leaving the ovary, or...
• Keeping the sperm from meeting the egg, or...
• Keeping the fertilized egg from attaching to the uterus (womb)

If you are already pregnant, emergency contraception will NOT work.

Who can use ECs?

If you had unprotected sex in the last 120 hours (5 days), EC may work for you.

Who should not take EC?

• Known or suspected pregnancy - EC does not work if you are already pregnant
• Hypersensitivity to any component of the product
• Undiagnosed abnormal genital bleeding

Is it OK to ECs repeatedly?

Yes! However, ECs are less effective at preventing pregnancy than other hormonal birth control methods. For the best pregnancy prevention, regular use of birth control is recommended.

When can I begin my birth control pills after I take ECs?

Ideally, as soon as possible after EC. We can help you get on the method that's right for you.

Will the ECs affect my ability to get pregnant in the future?

No, ECs do not affect your chances of getting pregnant in the future.

If I take it and I am already pregnant will it hurt the pregnancy?

If you are already pregnant, there is no documentation that EC will harm the fetus.

Remember: EC does not cause an abortion.
