The value of progesterone in early pregnancy is 25ng/ml is normal.
Before 8 weeks of pregnancy, progesterone is mainly secreted by the corpus luteum of pregnancy, after that the placenta is gradually formed, the progesterone secreted by the placenta gradually replaces the progesterone secreted by the corpus luteum of pregnancy, and the progesterone value of 25ng/ml and above before 12 weeks of pregnancy is in the normal range.
Progesterone is released in pulses, and the progesterone we measure is an instantaneous level that does not represent the average level in the blood, so progesterone cannot accurately predict the outcome of pregnancy.
Progesterone is not routinely measured in normal pregnancy, but it is recommended to take a progesterone test if you have abdominal pain, vaginal bleeding, etc. If your progesterone is low, don’t be overly nervous, and consult your obstetrician in a timely manner.
