Different methods can be used to predict the ovulation date:
- Calendar Method: In cases of regular menstrual cycles, the calendar method can be used to estimate ovulation. In this method, 14 days are counted backward from the first day of the last menstruation. However, this method may not always be accurate, as the length of the menstrual cycle can be affected by various factors.
- Ovulation Tests: Ovulation tests measure luteinizing hormone (LH) levels in urine to predict ovulation. LH levels peak 24–36 hours before ovulation. These tests are available over-the-counter at pharmacies.
- Basal Body Temperature Tracking: Basal body temperature is the temperature measured immediately upon waking. After ovulation, basal body temperature slightly increases due to the effect of progesterone. In this method, women measure their basal body temperature at the same time every morning and record it on a chart. A consistent rise in temperature indicates that ovulation has occurred.
- Cervical Mucus Monitoring: Women can track the color, consistency, and amount of cervical mucus to estimate ovulation. As ovulation approaches, cervical mucus becomes more abundant, clear, slippery, and elastic.
- Ultrasound Monitoring: Follicle development and egg release can be observed through ultrasound. This method is the most reliable way to accurately determine the ovulation date.
