Understanding Your Menstrual Cycle Phases
- Menstrual Phase: This is when your period occurs as the uterine lining sheds. It typically lasts 3-7 days.
- Follicular Phase: Follicles in your ovaries develop, and estrogen levels rise. This phase overlaps with the menstrual phase and continues until ovulation.
- Ovulatory Phase: A mature egg is released from the ovary. This brief phase usually occurs 14 days before your next period starts.
- Luteal Phase: Your body prepares for possible pregnancy. If fertilization doesn't occur, hormone levels drop, leading to the next menstrual phase.
