You may be confused with so many types of birth control pill because you may be looking at so many different brands. In general, estrogen and progestin pill are classified into monophasic, biphasic, or triphasic. Monophasic pill contain the same amount of estrogen and progestin in each active pill so it deliver constant dosages throughout the cycle. Biphasic pill contain different amount of estrogen and progestin in each active pill and it works by delivering fluctuates dosages during the cycle. Triphasic pill contain either the same or different amount of estrogen and different amount of progestin in each active pill. You need a prescription to use birth control pill so the first step is to consult with a gynecologist.
