If you experience irregular periods, it's important to speak with your healthcare provider to determine the underlying cause and receive appropriate treatment. In the meantime, you can keep track of your menstrual cycle by charting your periods on a calendar or using a menstrual tracking app. Some lifestyle changes that may help regulate your menstrual cycle include maintaining a healthy weight, eating a balanced diet, exercising regularly, reducing stress, and avoiding smoking and excessive alcohol consumption. Your healthcare provider may also recommend medications or hormonal therapies to help regulate your menstrual cycle.
