Under normal circumstances, the ovaries expel mature eggs every month, and the chances of conceiving during this period are higher than during intercourse, but it is not always possible to conceive, as many factors are involved. If you want to increase your chances of pregnancy, you can monitor ovulation through basal body temperature measurement or ovulation test paper to monitor ultrasound. If the basal body temperature is measured and menstruation is regular, the basal body temperature is usually lower than 36.5℃ in the first two weeks of ovulation and higher than 36.5℃ in the second two weeks of ovulation. The day when the hyperbolic curve of basal body temperature starts to get higher is the day of ovulation, or through ovulation test strips, the peak level of luteinizing hormone can be used to observe whether there is ovulation.
