Patient's question:
My period comes every month, but it always arrives early. Sometimes it comes right at the beginning of the month, and then it comes again at the end of the month. It's really annoying!What should I do in this situation?
Doctor's answer:
Hello, menstrual cycles within the range of 21-35 days are considered normal. The calculation method for the menstrual cycle is to start from the first day of bleeding during the previous period and end on the day before the next period, which constitutes one menstrual cycle. As long as your menstrual cycle falls within the normal range, it is considered normal and does not require intervention. Menstrual cycles are not exactly the same every month and may vary by about one week before or after due to changes in factors such as the environment and emotions.
