The progesterone level in a woman’s body varies at different weeks of pregnancy, ranging from 63.4-94.5 nmol/L in early pregnancy, 95-150 nmol/L in mid-pregnancy, and 150-1500 nmol/L in late pregnancy. Progesterone values are different in each stage of pregnancy, so if abnormalities occur during pregnancy, you can go to the hospital to test the progesterone value, especially in the early stages of pregnancy, if there is low progesterone and vaginal bleeding, you should promptly replenish progesterone, and if necessary, inject progesterone to protect the fetus to avoid the possibility of preterm abortion. During pregnancy, the blood glucose level should be checked frequently to avoid gestational diabetes, and the blood pressure should be checked to avoid gestational hypertension, which may lead to a large fetus or fetal hypoxia.
