5 side effects of taking birth control pills frequently

Birth Control Pills (BCPs) were introduced to help with population control and family planning issues. Soon, they became an alternative to condoms and the diaphragm. While they are completely safe and approved by the Food and Drug Administration (FDA), just like any drug, they also come with potential side effects and risks. These pills, also known as oral contraceptives, contain synthetic versions of the hormones progestin and estrogen. The ovaries naturally produce these hormones. BCPs can contain only progestin or they can contain both hormones. Both hormones suppress ovulation or the release of an egg during a woman’s menstrual cycle. They accomplish this by upsetting the body’s normal hormonal balance. This hormonal imbalance can negatively affect her body.
