Approximately 99 percent of obstetricians and gynecologists believe that suppressing a menstrual period through the use of birth control pills is safe, according to a 2003 Gallop survey conducted by the American Congress of Obstetricians and Gynecologists 1. With their doctor's support and reassurances, more women are considering this option for themselves. However, before implementing this approach, all women should take time to learn about potential side effects.
Bleeding or spotting in between menstrual periods, also referred to breakthrough bleeding, may be more common for women who use birth control pills to delay or suppress their periods. The frequency and amount of this bleeding will vary depending upon the individual woman, but often the flow is light and brownish in color. Although many women find delaying or surpressing their periods convenient, this breakthrough bleeding can be anything but. However, the University of Michigan Health Systems suggests that allowing a menstrual cycle to occur at least once every three to four months may lessen the frequency or intensity of this bleeding 2. It also may lessen as the woman's body adjusts to the hormones, explains the Mayo Clinic. However, any breakthrough bleeding that is particularly intense or bothersome should be reported to a doctor.

These include a reduction or elimination of the symptoms of premenstrual syndrome as well as few perimenopausal symptoms. Menstrual migraines, endometriosis and acne can also be reduced. Also, the Association of Reproductive Health Professionals states that there is also an increased feeling of well-being for many women 4.
