What is the normal progesterone level at 5 weeks of pregnancy?

During pregnancy, people will always face various physical problems, which will have a great impact on their bodies. It is necessary to choose appropriate treatment methods according to personal physical conditions. Generally, people will pay special attention to the normal value of progesterone at five weeks of pregnancy. In fact, the normal value of progesterone depends on personal physical conditions. Everyone's physical manifestations and types are different.

During pregnancy, HCG in a woman's body stimulates the corpus luteum to produce progesterone; from 7 to 9 weeks, it gradually transitions to placental production, also known as luteal placental transfer; from 10 to 11 weeks, the placenta's progesterone production increases significantly, at which time the placental trophoblast takes over from the corpus luteum to produce progesterone and maintain pregnancy. Progesterone test is mainly used to understand the function of the corpus luteum, whether the ovaries have ovulated, and understand the pregnancy status.

The normal progesterone value is the same at different weeks of pregnancy, so what is the normal HCG value after pregnancy? During normal pregnancy, the serum HCG value is directly related to the gestational age. The HCG (IU/L) value will certainly be different at different gestational ages, and will show a positive increasing trend.

For example, 0.2-1 weeks of pregnancy, the HCG value is 5-50; 1-2 weeks of pregnancy, the HCG value is 50-500; 2-3 weeks of pregnancy, the HCG value is 100-5000; 3-4 weeks of pregnancy, the HCG value is 500-10000; 4-5 weeks of pregnancy, the HCG value is 1000-50000; 5-6 weeks of pregnancy, the HCG value is 10000-100000; 6-8 weeks of pregnancy, the HCG value is 15000-200000; 2-3 months of pregnancy, the HCG value is 10000-100000. If the progesterone level is low, it can easily lead to threatened miscarriage in women in the early stages of pregnancy, causing irregular vaginal bleeding or even direct miscarriage.

However, in the entire menstrual cycle of a normal non-pregnant woman, the progesterone level is lowest before ovulation, begins to rise after ovulation, and is highest during the luteal phase. Before ovulation, the progesterone level in body fluids should be less than 2 ng/mL, and after ovulation it should be greater than 5 ng/mL. If you are pregnant, the progesterone level will initially remain at the level of the luteal phase. After the placenta is formed, the hormones secreted by the placenta will increase the progesterone level in the pregnant woman's body to 100-200 ng/ml, which is dozens to hundreds of times that of non-pregnant women.
