Ovulation day calculation method

Methods for calculating ovulation day mainly include the following: 1. Menstrual cycle calculation method: For women with regular menstrual cycles, ovulation usually occurs approximately 14 days before the next menstrual period. The five days before ovulation, the four days after, and the ovulation day itself constitute a 10-day ovulation period. 2. Ovulation test strip method: This involves using ovulation test strips to detect luteinizing hormone (LH) levels in urine. LH typically peaks 1–2 days before ovulation, and a strongly positive test result indicates that ovulation is imminent. 3. Basal body temperature (BBT) measurement method: Measure and record your body temperature every morning upon waking. Basal body temperature rises by 0.3–0.5°C during ovulation; however, this method cannot predict the exact timing of ovulation in advance. 4. Cervical mucus observation method: During the ovulation period, vaginal discharge increases in volume, becomes clear and watery, and exhibits stretchy, egg-white-like characteristics. Ovulation typically occurs within ±48 hours of the last day when transparent, stretchy mucus is observed. These methods can be selected according to individual circumstances, or combined for a more accurate assessment of ovulation day.
