Unscheduled vaginal bleeding or spotting may occur while you are taking birth control pills. Unscheduled 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. Such bleeding may be temporary and usually does not indicate any serious problems. If the bleeding occurs in more than one cycle or lasts for more than a few days, talk to your healthcare provider.
Ectopic pregnancy (pregnancy outside the womb) as well as intrauterine pregnancy (pregnancy inside the womb) may occur in birth control failures.
The most common side effects of oral contraceptives are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses.
The use of oral contraceptives is associated with increased risks of several serious side effects, including high blood pressure, blood clots in the legs (thrombophlebitis) or lungs (pulmonary embolism), blockage 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, oral contraceptives can cause liver tumors which may rupture and cause severe bleeding.
