The fertility cycle, also known as the menstrual cycle, is a recurring sequence of physiological changes in a woman's body that prepares it for a possible pregnancy. Understanding these changes is key for both conception planning and general reproductive health.

The fertility cycle can be divided into four distinct phases:
- Menstruation: This is when the uterine lining sheds, resulting in a period. It typically lasts from 3 to 7 days.
- Follicular Phase: This phase starts with menstruation and continues until ovulation. During this time, the uterine lining thickens, and follicles in the ovaries develop.
- Ovulation: A mature egg is released from one of the ovaries, usually around the midpoint of the cycle. This is when you are most fertile. The https://www.pregnancy-calculator.org tool can accurately pinpoint these critical days, enhancing your chances of conception.
- Luteal Phase: After ovulation, the egg travels to the uterus, and the uterine lining continues to thicken in preparation for implantation. If pregnancy doesn't occur, the cycle starts again.
Key Hormones in the Fertility Cycle
The fertility cycle is governed by a delicate interplay of hormones, including:
- Follicle-Stimulating Hormone (FSH): Stimulates follicle growth in the ovaries.
- Luteinizing Hormone (LH): Triggers ovulation.
- Estrogen: Regulates ovulation and thickens the uterine lining.
- Progesterone: Prepares the uterine lining for embryo implantation.
Calculating Your Fertile Window
Your fertile window includes the days leading up to and including ovulation, as sperm can survive for several days in the female reproductive tract. Using our Pregnancy Calculator & Ovulation Estimator, you can pinpoint your fertile window based on your cycle length. The interactive calendar color-codes your period days, fertile window, and peak ovulation day for easy planning.
Tracking Ovulation Signs
Besides using a calculator, tracking physical signs can also help you identify your fertile window:
- Cervical Mucus Changes: Before ovulation, you may notice an increase in clear, slippery vaginal discharge, resembling egg whites.
- Basal Body Temperature (BBT): A slight increase in BBT can indicate ovulation.
- Ovulation Predictor Kits (OPKs): These kits measure luteinizing hormone (LH) levels in urine to predict ovulation.
