You should speak with your doctor
about all of this, as it is important to make sure that you are following your provider's recommendations. Most hormonal birth control
, such as oral contraceptive pills (OCPs), work in some way by affecting the normal menstrual cycle. This cycle is generally tightly regulated by the body to enhance fertility. As the goal of OCPs and other contraceptives is to decrease fertility, one of the ways that it does that is by adjusting your menstrual cycle, or rather, by either directly changing it or by causing alterations in other hormones that change your menstrual cycle. If you are on birth control pills, most women will not undergo the hormonal and physical changes that entail a normal menstrual cycle at all, despite the familiar pattern of a roughly normal cycle with regards to the timing. The pills instead induce other changes. If you stop taking them and are not pregnant, it is possible that eventually your body will return to its previous cycle. You need to weigh the risks and benefits of this however, and for that you need to talk to your doctor. Please speak with your doctor about your question.
