If you have had unprotected sex, or if the condom you were using broke, if you act quickly, then emergency contraception will usually prevent a pregnancy. There are two methods of emergency contraception, namely pills containing the hormone progestogen, and the IUD or intrauterine device. The pills should be taken within three days of unprotected sex, and the IUD fitted within five days of unprotected sex.
The sooner the pills are taken, the more effective they are. If taken within 24 hours after sex, nine out of ten pregnancies are prevented. The pills stop or delay ovulation, and prevent an egg from settling in the womb. After taking the pill, you normally get your periods within a few days of when you expect it.
If inserted within five days of unprotected sex, an IUD is 98% effective. They are fitted by a trained doctor or nurse and can be removed during your next period if you prefer. IUD’s stop and egg from being fertilised and settling in the womb.
