what are birth control pills and how do they work?

 There are two types of birth control pills: the combined pill and the mini-pill. The combined pill contains two hormones, estrogen and progestin. These hormones work together to prevent pregnancy by thickening the mucus in the cervix, which makes it difficult for sperm to penetrate and fertilize an egg. The mini-pill contains only progestin. This hormone thickens the mucus in the cervix, which makes it difficult for sperm to penetrate and fertilize an egg.

Emergency contraception is a method of birth control that can be used after unprotected sex or failure of another birth control method. Emergency contraception is not as effective as regular birth control. There are two types of Emergency Contraception: the emergency contraceptive pill and the copper intrauterine device (IUD). The emergency contraceptive pill contains progestin, which works to prevent pregnancy by delaying or inhibiting ovulation. The copper IUD is a small, T-shaped device that is inserted into the uterus by a healthcare provider. The copper in the IUD prevents pregnancy by inhibiting sperm motility and fertilization of an egg. Emergency contraception should not be used as a regular method of birth control.
