What is the normal progesterone level for pregnant women?

Women's fertility and fetal growth after pregnancy are inseparable from progesterone, so progesterone is very important for women. If there is too much lack of progesterone during pregnancy, miscarriage may occur. Some women who hope to have children later can also inject a large amount of progesterone, which can have a certain contraceptive effect.

Normal reference value of progesterone:
