You might seek emergency contraception (EC) to reduce the likelihood of becoming pregnant after unprotected or inadequately protected sexual intercourse, such as:

• Engaging in sexual activity without the use of any birth control method.
• Having sexual intercourse when a chosen birth control method failed (such as a condom breaking) or was used incorrectly (like missing several birth control pills).
• Using a less effective form of contraception, such as a barrier method.
• Engaging in sexual activity during fertile days as determined by your menstrual cycle, often tracked using calendars or period-tracking apps.
