What is ovulation period calculation method? The ovulation period for women with regular menstrual cycles is generally 14 days before their next period, and the ovulation period is obtained by subtracting 14 days from the menstrual cycle.

The Aquino method, also known as the mathematical formula method, means that ovulation occurs approximately 14 days before the last day of the menstrual cycle (i.e. the first day of the next menstrual cycle). If the day of the next menstrual cycle is on the Nth day, then this ovulation day is on the N-14th day.
2. Ovulation test strip method
The luteinizing hormone (LH) in female urine reaches its peak 24-48 hours before ovulation, and ovulation test strips can accurately detect the peak level of LH. After starting the detection, it should be checked regularly every day. When a color close to the peak value is about to appear, it should be tested every 12 hours until the LH peak is detected.
3. Basal body temperature measurement method
Measure basal body temperature continuously for six to twelve months and record it. Basal body temperature will increase by 0.3-0.5 ℃ after ovulation. Pregnant women can purchase a thermometer and drop it below 35 ℃ before going to bed every day. They should wake up every morning (after 6-8 hours of sleep) without any exercise and immediately measure their body temperature.
