Ovulation tracking is the process of monitoring your menstrual cycle to identify your fertile window and ovulation day. Our tracker uses your cycle length and period data to predict when you're most likely to ovulate, typically around day 14 of a 28-day cycle. The tool calculates your fertile window (usually 5-6 days including ovulation day) and provides hormone level estimates to help you understand your body's natural rhythms. This information is valuable for family planning, health monitoring, and understanding cycle irregularities.
