There are so many different type of birth control pills on the market; some allowing you to have a period every three months, others eliminating them completely. These pills contain a very low dose of estrogen and a different type of synthetic progesterone called progestin that have decreased side effects like bloating, fluid retention and weight gain. While you get less periods during the year, you are more likely to get bleeding or spotting between periods. The amount of bleeding can vary, but it should decrease over time. Like all birth control, these medications have serious risks including blood clots. If you smoke or you’re over 35, these risks increase. If you’re seriously considering taking this medication make sure you speak to your doctor about your individual risk.
