Understanding Your Menstrual Cycle

The menstrual cycle is a series of changes a woman's body undergoes each month in preparation for a possible pregnancy. It's typically counted from the first day of one period to the first day of the next. The average cycle lasts about 28 days, but can vary.

  • Menstrual Phase: The start of your cycle, when you have your period.
  • Follicular Phase: The phase where the lining of the uterus thickens and an egg prepares to be released.
  • Ovulation Phase: When an egg is released from the ovary, marking your most fertile time.
  • Luteal Phase: The phase after ovulation, where the body prepares for a possible pregnancy. If pregnancy doesn't occur, the cycle restarts.

Using a menstrual phase calculator can help you pinpoint these phases accurately.
