Birth control pills are a kind of medicine with hormones that you take every day to prevent pregnancy. There are many different brands of pills. The pill is safe, affordable, and effective if you always take it on time. Besides preventing pregnancy, the pill has lots of other health benefits, too.
The birth control pill works by stopping sperm from meeting an egg (which is called fertilization). The hormones in the pill stop ovulation. No ovulation means there’s no egg hanging around for sperm to fertilize, so pregnancy can’t happen. The pill’s hormones also thicken the mucus on the cervix. Thicker cervical mucus makes it hard for the sperm to swim to an egg — kind of like a sticky security guard.
