Your "fertile window" is only about 6 days per cycle: the 5 days leading up to ovulation and the day of ovulation itself. Using an **ovulation predictor** or **ovulation estimator** and identifying your **ovulation days** is key for family planning, whether you are trying to conceive or avoiding pregnancy.
The 3 Key Fertility Signs
Cervical Mucus Analysis
As you approach ovulation, estrogen causes discharge to become clear, slippery, and stretchy (like raw egg whites). This is nature's way of helping sperm survive.
Basal Body Temperature (BBT)
Your resting temperature spikes slightly (about 0.5-1°F) after ovulation. Tracking this daily helps confirm that ovulation has actually occurred.
Cervical Position (SHOW)
Near your most fertile days, the cervix becomes Soft, High, Open, and Wet. This 'SHOW' acronym is a reliable indicator of hormonal readiness.
