Progestin-only ECPs reduce the risk of pregnancy by 89 percent. Only one woman out of 100 will become pregnant after taking progestin-only ECPs. The closer a woman is to ovulation at the time of unprotected intercourse, the greater her chances of pregnancy. Emergency IUD insertion reduces the risk of pregnancy by 99.9 percent. Only one out of 1,000 women will become pregnant after emergency IUD insertion.
Emergency contraception is meant for emergencies only.
ECPs do not continue to prevent pregnancy during the rest of the cycle. Other methods of birth control must be used. Emergency contraception offers no protection against sexually transmitted infections. Consider testing for sexually transmitted infections if there is a possibility that unprotected sex put you at risk. Some clinics and clinicians will prescribe ECPs over the phone and call the prescription in to a pharmacy.
