The standard of progesterone value is different in different stages of women’s pregnancy, so it should be judged according to their own body condition. Usually the progesterone value is about 52-100nmol/L in about one week of pregnancy, about 130-160nmol/L in about one month of pregnancy, and about 480-777nmol/L in about 9 months of pregnancy. Women should not only know their progesterone value regularly after pregnancy, but also take care of their body in time. If the progesterone value is low, they should take progesterone or inject progesterone appropriately to avoid a series of early miscarriage or pre-eclampsia miscarriage.
