When the condom breaks or you just forget to use protection, you have a couple different options. For one, do remember that the listed options only cover the chance of pregnancy; they will not cover any STIs, so seek further protection if you were put at chance for exposure of STIs. For one, you can take the Emergency Contraception Pill which is effective up to 72 hours after sex (but is more effective the sooner it is taken). It is supposed to be about 75% to 89% effective (though it's hard to know exact numbers because of the nature of the morning-after pill). The side effects of the ECP are usually nausea and vomiting. Another lesser-known alternative is an Emergency IUD insertion. An IUD is usually used for planned contraception, but it can be inserted in an emergency to be 99.9% effective at preventing an unwanted pregnancy.Learn more sex facts like this in the The Big Bang book by Em and Lo.Have you ever (or your partner) had to use Emergency Contraception?
