For women preparing for pregnancy, the most important thing is to calculate their ovulation period. When a woman's menstrual cycle is regular, it is easy to calculate the ovulation period. However, some female friends have a short menstrual cycle, how should ovulation be calculated? Next, please follow the encyclopedia to learn more!
1. Aquino method: Aquino method, also known as mathematical formula method, means that ovulation day is 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 will 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.
4. Observation method of vaginal discharge: During a menstrual cycle, the nature of vaginal discharge will undergo periodic changes. In general, vaginal discharge is relatively dry, viscous, and in small quantities. During ovulation, vaginal discharge becomes clear and transparent, like egg whites, with a high degree of stringiness. This is due to the high concentration of estrogen produced during ovulation, which acts on the columnar epithelial cells of the cervical opening, causing them to secrete a large amount of vaginal discharge.
