Dear a54321,

No. Using emergency contraception (EC) more than once does not affect a woman's fertility — it will not prevent her from becoming pregnant in the future.

Women should feel free to use EC whenever they think it's necessary. EC is not recommended as an ongoing form of birth control because it is not as effective at preventing pregnancy as birth control methods like the patch, pill, ring, or shot. Also, frequent use of EC may cause periods to become irregular and unpredictable.

EC can reduce the risk of pregnancy if started within 120 hours of unprotected vaginal intercourse. The sooner it is taken, the better. If started within 72 hours of unprotected sex, it can reduce the risk of pregnancy by 75 to 89 percent.

To get EC, call 1-800-230-PLAN to find a Planned Parenthood health center near you.

Hope this information helps!

Take care,
