Emergency Contraception Directory
There are two types of emergency contraception: emergency contraceptive pills (ECPs); and intrauterine devices (IUDs).
ECPs use the same hormones in some brands of regular birth control pills, but in higher doses. Some ECPs are "combined ECPS" with progestin and estrogen. Others are progestin-only (for breastfeeding mothers, or if you can’t take estrogen). ECPs can work up to 5 days postcoital.
An IUD is a plastic device which may be placed into the uterus (womb) by a doctor within five days after having sex. The IUD keeps the sperm from meeting the egg, or keeps the egg from attaching to the wall of the uterus.
