It is generally not recommended to routinely check progesterone during pregnancy, and dynamic monitoring of blood beta-HCG level is optional before 8-10 weeks of pregnancy to understand embryonic development. During pregnancy, generally the blood beta-HCG value will double every one or two days before 8 weeks of pregnancy, such value indicates that the embryo development is relatively good, and if the blood beta-HCG is ideal, HCG itself can also secrete part of progesterone, but progesterone generally does not change much with the growth of pregnancy week, often remains stable or even decreases, and will reach the lowest at 7 weeks of early pregnancy. 6 weeks of progesterone can generally If it is low and there is abdominal pain or vaginal bleeding, the clinical practice is to give progesterone injection of 20 mg or 40 mg once a day, or progesterone capsules twice a day, 2 to 4 capsules a day, or oral dydrogesterone tablets twice a day, 1 tablet a day, until the symptoms disappear for 2 weeks or until the pregnancy reaches about 4 months. Progesterone greater than 25ng/ml indicates a viable intrauterine pregnancy, which of course will eventually need to be determined by ultrasound; if it is less than 5ng/ml, it indicates a poor resolution of this pregnancy. Therefore, the progesterone at 6 weeks should preferably be around 20ng/ml, if it is too low you can supplement progesterone after determining that it is intrauterine pregnancy. It is forbidden to have intercourse in early pregnancy, especially if the phenomenon of brown discharge should be absolutely bed rest, do not eat spicy and stimulating hair, but do not be too nervous, keep a good state of mind.
