At the time of ovulation, the body temperature will rise 0.3-0.5℃ above the basal body temperature. When measuring the basal body temperature, we need to pay attention to the fact that every day after we open our eyes, we can’t engage in any activities, can’t go to the toilet, brush our teeth, wash our face, and the body temperature measured at this time is our basal body temperature. Before ovulation, the basal body temperature begins to rise, the range of increase is about 0.3-0.5 ℃, so in the ovulation period our basal body temperature is maintained to 36.7-37.2 ℃ between. In the ovulation period, the elevated basal body temperature will last for about two weeks, and if there is no conception in this month, the temperature will drop. You can infer your ovulation period by measuring your basal body temperature, and you can also choose to go to the hospital for ultrasound to monitor ovulation. If you want to use ultrasound to monitor ovulation, it is generally recommended that you start going to the hospital for ultrasound every other day on the eighth day of your menstrual period, and you can find out how the follicles are developing by checking the ultrasound.
