The normal range of progesterone in the first trimester of a woman’s pregnancy is 4.73-50.74 ng/ml. There is no fixed value for HCG, which should be doubled every other day to be normal. Progesterone is an important progesterone that 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 the value of progesterone is low, there may be a possibility of preeclampsia. At 1-2 weeks of pregnancy, HCG value may be 5-50IU/L; at 3-4 weeks of pregnancy, HCG value may be 500-10,000IU/L. Under normal circumstances, HCG usually doubles in value in about 2-3 days, which indicates that the embryo is developing well. However, at 8-10 weeks of pregnancy, blood HCG has already reached its peak, and after that, it may increase more slowly and remain at a certain level. If you find progesterone and HCG values deviate from the normal range during the pregnancy test, it is recommended to consult a doctor in time, complete the relevant examinations under the doctor’s guidance, identify the cause of the disease, and provide symptomatic treatment.
