Irregular vaginal bleeding or spotting may occur while you are taking birth control pills. Irregular bleeding occurs most often during the first few months of oral contraceptive use, but may also occur after you have been taking the pill for some time. If the bleeding occurs in more than one cycle or lasts for more than a few days, talk to your healthcare provider.
If you have not taken the birth control pills daily as instructed and missed a menstrual period, or if you missed two consecutive menstrual periods, you may be pregnant. Check with your healthcare provider immediately to determine whether you are pregnant. Do not continue to take oral contraceptives until you are sure you are not pregnant, but continue to use another method of birth control.
The most common side effects of birth control pills are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses.
Use of the birth control pill is associated with increased risks of several serious side effects, including high blood pressure, blood clots in the legs (thrombophlebitis) or lungs (pulmonary embolism), stoppage or rupture of a blood vessel in the brain (stroke), blockage of blood vessels in the heart (heart attack or angina pectoris), or other organs of the body. In rare cases, the birth control pill can cause liver tumors which may rupture and cause severe bleeding.
