Birth Control Method
Hormonal
Description
Combined oral contraceptives are birth control pills that contain two hormones, an estrogen and a progestin. The estrogen prevents pregnancy by stopping ovulation (release of an egg), while the progestin makes the lining of the uterus thinner, preventing fertilization.
How It Works
Combined oral contraceptives must be taken at the same time every day. You cannot miss pills or you risk pregnancy. You must see a health-care professional to get the Pill, and it's advisable to use a second form of contraception for the first seven days of your first pack of pills. During the fourth week, you will either take an iron pill that is a different color, or no pill at all. During this time, you will experience a menstrual period.
Should You Use It?
Combined oral contraceptives are one of the most effective methods of contraception, but do not protect against the transmission of sexually transmitted infections (STIs). Also, some women have experienced unpleasant reactions to the Pill. However, this form of contraception has numerous perks, including improvement of acne, reduced blood flow during menstruation, and less painful cramps. If you have a monogamous partner who has tested negative for STIs, you might want to try the Pill.
Effectiveness
Among typical couples who use combined pills, about 5% will experience an accidental pregnancy in the first year. If pills are used consistently and correctly, just one in 1,000 women will become pregnant.
STI Protection
Combined oral contraceptives do not prevent the transmission of sexually transmitted infections, including HIV.

Follow Up
Many women feel they cannot take combined oral contraceptives because of their bodies'
response to the Pill. If you have tried the Pill and don't like it, you might try
another brand or dosage, or try the mini-pill.
