Understanding your menstrual cycle is key whether you're planning for pregnancy or simply want to stay informed about your body. A 28-day menstrual cycle is often considered the "average", but remember that cycle lengths can vary.

The menstrual cycle is a recurring process, typically around 28 days, where a woman's body prepares for a potential pregnancy. It involves the maturation and release of an egg (ovulation) and the thickening of the uterine lining. If pregnancy doesn't occur, the lining sheds, resulting in menstruation (your period).
Key Phases of a 28-Day Cycle:
- Menstruation (Days 1-5): This is when you experience bleeding. Day 1 is the first day of your period.
- Follicular Phase (Days 1-14): The lining of the uterus thickens. An egg-containing follicle in the ovary matures.
- Ovulation (Around Day 14): The mature egg is released from the ovary. This is when you are most fertile.
- Luteal Phase (Days 15-28): The body prepares for possible implantation of a fertilized egg. If fertilization doesn't happen, hormone levels drop, and the cycle begins again with menstruation.
