1. How does emergency contraception work

2. Emergency contraception works to prevent unwanted pregnancy after unprotected sex. There are 2 types of Emergency Contraception. 1. 2. Emergency Contraceptive Pills Intrauterine Device IUD

3. Emergency contraceptive pills, commonly known as the ‘Morning After Pill’, or through its brands (Plan B, iPIll, Unwanted72), are used to prevent undesired pregnancy during unprotected intercourse or in case your birth control strategy fails. The active element in all of these pills is a hormone called Levonorgestrel, a type of estrogen. To avoid unwanted pregnancy, emergency contraceptive pills must be taken within 72 hours or three days after unprotected intercourse

4. Emergency contraceptive pills prevent conception in different ways depending on where you are in your menstrual cycle. It inhibits you from ovulating if you haven't already. This would cause the ovulation cycle to be pushed back, preventing or delaying the release of an egg. If you've already ovulated, these pills make the uterus a hostile environment for fertilization and implantation. An ECP may not help prevent pregnancy after unprotected sex if it is taken beyond 72 hours (3 days). Remember that the emergency contraceptive pill has a 10-18% probability of failure.

5. You can use the Intrauterine Device (IUD) as emergency contraception if 72 hours(3 days) have passed but it's not 120 hours (5 days). There is also the ulipristal acetate pill (Ella) as an option. This must also be taken within 5 days of sex without protection. However, because ulipristal acetate has yet to be licensed in India, those who wish to use it after 72 hours but before 120 hours must use an IUD. Even if the IUD is inserted after intercourse, the copper in it prevents pregnancy. You cannot, however, insert the IUD yourself; instead, you must go to a gynecologist, nurse, or other women's health care provider who can do so
