It is not uncommon for women to experience a missed period while taking birth control pills, especially if they have been taking them as prescribed. If you are concerned about a possible pregnancy, it is recommended to take a pregnancy test. Additionally, if the lack of menstruation persists, it would be a good idea to discuss this with your doctor to explore other possible causes and solutions. Remember that changing the type or strength of hormones in your pill can sometimes help regulate your menstrual cycle. It is important to continue taking your current pill as directed, as the absence of bleeding does not affect its effectiveness.
