The normal value of progesterone is around 20 ng/mL when the menopause is 35 days and the pregnancy is confirmed. After pregnancy, progesterone secretion will increase, and there will also be an increase in chorionic gonadotropin levels, but progesterone secretion has a certain degree of volatility, sometimes high and sometimes low, unlike chorionic gonadotropin, which doubles in size every other day. When pregnancy is detected, one should go to the Obstetrics and Gynecology Department of the hospital in a timely manner to check the progesterone level. If the value of progesterone is found to be less than 20 ng/mL, it suggests that there may be a case of embryonic dysplasia, and one should pay attention to rest and closely monitor the levels of progesterone and chorionic gonadotropin. When the progesterone level is low, it is recommended to consult a regular hospital in time, do not blindly self-medication, so as not to cause adverse consequences.
