Through the basal body temperature test and blood test, you can know whether you have enough progesterone or not. Under normal circumstances, a woman’s basal body temperature is relatively low before ovulation, and the basal body temperature rises after ovulation because the corpus luteum formed after ovulation and the secretion of more progesterone stimulate the hypothalamic thermoregulatory center, resulting in an increase in the basal body temperature. A woman’s typical biphasic temperature basically indicates that the level of progesterone is normal, but it’s not accurate, and it may be different. The accuracy of the patient’s progesterone level can be determined by drawing blood for progesterone level, which can be done one week before menstruation. Progesterone levels vary at different stages of the menstrual cycle. Blood levels of progesterone are lower during the follicular phase, then gradually increase, and progesterone levels continue to rise after ovulation. Checking the level of progesterone can provide a preliminary understanding of the ovarian function and the development of the embryo after pregnancy. Low levels of progesterone can be supplemented under the guidance of a doctor, such as with progesterone and dydrogesterone tablets.
