The range of basal body temperature after pregnancy is between 36.5-37.2℃. If the temperature exceeds 37.3℃, it means something else is going on. The method of measuring the basal body temperature is to wake up every morning without engaging in any activities, going to the toilet, brushing teeth or washing face, and the temperature measured at this time is our basal body temperature. At the time of ovulation, the basal body temperature begins to rise slowly, the range of increase is 0.3-0.75 ℃, but the highest temperature should not be more than 37.3 ℃, which proves that the ovulation period has arrived. If there is no pregnancy this month, our basal body temperature will start to slowly decline again by 0.3-0.5 degrees after maintaining it for about a week. If no drop occurs. It still stays between 36.5-37.2 degrees Celsius, it means there is a possibility of pregnancy.
