Whether progesterone 13ng/ml is normal in early pregnancy needs to be analyzed together with the blood HCG value as well as the week of pregnancy, and cannot be generalized.
Progesterone is an important progesterone, which not only plays an important role in the regulation of the menstrual cycle, but is also a hormone necessary for the maintenance of pregnancy. If progesterone is lowered an immune rejection of the fetus by the mother occurs and there is a risk of miscarriage.
If you are newly pregnant, a progesterone level of 13 ng/ml is within the normal range because this is when the blood HCG values as well as the progesterone values are just beginning to increase. As the weeks of pregnancy increase, the HCG and progesterone values will gradually increase. If you are 6-8 weeks pregnant and have a progesterone of 13ng/ml, then this progesterone value is on the low side.
If the value of progesterone is low in early pregnancy, it is recommended to consult a doctor in time to improve the examination and timely treatment.
