Ovulation typically occurs around the middle of a woman's menstrual cycle, usually about 14 days before her next period. For those with a regular 28-day cycle, ovulation usually happens around day 14. However, it's important to note that the exact timing can vary from woman to woman and cycle to cycle. The fertile window, which is the timeframe when conception is most likely to occur, includes the days leading up to and including ovulation. This typically spans around 5 to 7 days in the menstrual cycle. Tracking ovulation through methods like monitoring basal body temperature, cervical mucus, and ovulation predictor kits can help pinpoint the most fertile days within this window.
