The menstruation cycle is a complex, natural process your body undergoes each month, preparing for a possible pregnancy. It's measured from the first day of your period until the day before your next period begins. While the average cycle is 28 days, it can vary significantly among individuals, ranging from 21 to 35 days. Understanding the different phases can empower you to plan for conception or manage your reproductive health.

-
Menstruation (Period): This is when the uterine lining sheds, resulting in bleeding. It typically lasts 3 to 7 days.
-
Follicular Phase: Starting on the first day of your period, this phase lasts about 13-14 days. Hormones stimulate the uterus lining to thicken, and follicles begin growing on the ovaries, with usually only one maturing into an egg.
-
Ovulation: A mature egg is released from an ovary, usually about two weeks before your next period. This is when you are most fertile.
-
Luteal Phase: Following ovulation, the egg travels to the uterus. The uterine lining continues to thicken in preparation for pregnancy. If pregnancy doesn't occur, the cycle restarts with menstruation.
What is Ovulation?
Ovulation is the release of a mature egg from the ovary. This crucial event happens roughly mid-cycle and represents the peak of your fertile window. If you're trying to conceive, knowing when you ovulate is key.
Predicting Ovulation
Several methods can help predict ovulation, including:
- Tracking your cycle length: Use a pregnancy calculator to log the first day of your period for several months to identify patterns and estimate ovulation.
- Monitoring cervical mucus: Observe changes in vaginal discharge. It becomes thin, clear, and slippery, like egg whites, just before ovulation.
- Using ovulation predictor kits (OPKs): These kits measure luteinizing hormone (LH) levels in your urine, which surge 24-36 hours before ovulation.
