What is it?
Combined pills contain the hormones estrogen and progesterone.
Some brands contain 21 pills with hormones and 7 without hormones (placebo pills). Your period comes when you’re taking the hormone-free pills. Newer brands have more hormone pills. Other brands have fewer (or even zero) placebo pills.
How well does it prevent pregnancy?
An effective form of birth control, but not as reliable as implant, hormonal IUD, copper IUD, or sterilization for men or women.
About 7 out of 100 women using combined pills get pregnant in a year of use.
HOW DOES IT WORK?
Prevents the release of an egg from the ovaries each month (ovulation). Progesterone also thickens the mucus in your cervix. This stops sperm from entering the uterus. The lining of the uterus also becomes thinner.
