What is the normal progesterone level at 40 days of pregnancy?

Under normal circumstances, women have been paying attention to various indicators of their body since pregnancy, worrying that insufficient indicators will lead to malnutrition of the fetus. In fact, everyone's physical fitness is different. Generally, the normal progesterone value should be around 40. If the progesterone value is low, it is not good for the baby. You should go to the hospital for progesterone copper injection and rest in bed more. This can provide support and protection for the early growth and development of the fetus, and can have a certain calming effect on the uterus. This thing must reach a certain amount, not too little. So how much is the normal value of progesterone at 40 days of pregnancy?

How much is the normal value of progesterone at 40 days of pregnancy

Around 40 days of pregnancy, the progesterone value should be around 40, which is considered normal. If the progesterone value is slightly lower, it is easy to cause miscarriage. Pay attention to replenish it in time. If the value is too different, consider intramuscular injection of corpus luteum copper, which can promote the growth of the fetus and avoid unexpected situations due to insufficient corpus luteum.

There are two sources of progesterone during pregnancy: one is produced by the corpus luteum of the ovary, and the other is secretion by embryonic trophoblasts. After 6-8 weeks of pregnancy, the progesterone level produced by the corpus luteum of the ovary gradually decreases, and is later replaced by the progesterone level produced by the embryo. If the connection between the two is unbalanced, miscarriage is likely to occur. The metabolism of progesterone is closely related to miscarriage. The normal value of progesterone is 32.6-139.9 nmol/L during 6 to 13 weeks of pregnancy.

At 40 days of pregnancy it is 24.5±7.6ng/ml. Excessive secretion of progesterone can cause poor decidual reaction during pregnancy, affect the implantation and growth of the fertilized egg and embryo, and cause miscarriage.

In the entire menstrual cycle of a normal non-pregnant woman, the estrogen level is the lowest before ovulation, begins to rise after ovulation, and reaches the highest level during the follicular phase. Before ovulation, the progesterone level in the blood should be less than 2 μg/ml, and after ovulation it should be higher than 5 μg/ml. If you get pregnant, the estrogen level will initially remain at the level of the follicular phase, and when the embryo is born, the growth hormone secreted by the embryo will increase the progesterone level in the pregnant woman's body to 100-200 lac/ml, which is dozens to thousands of times that of a non-pregnant woman.

Generally, the standard value of progesterone in women's follicular phase is 0.6~1.9nmol/L; the standard value in the ovulation phase is 2.40~9.40nmol/L; the standard value after ovulation is 20.7~102.4nmol/L. The progesterone value can be checked to see if it is normal. The progesterone value test is done by extracting venous blood from the expectant mother. Since the composition of the progesterone value is not affected by meals, the progesterone value test does not require fasting. At the same time, you can drink water for the progesterone value test. Generally, after checking in the morning, the results can be obtained at noon. In the early stages of pregnancy, the progesterone value should remain high. If you compare two progesterone test results and find that the progesterone value is lower than the previous one, it is very likely that there is an ectopic pregnancy or a problem with the embryonic development, and further examination is needed. The blood progesterone level of patients with ectopic pregnancy is low, which is medically recognized, so the progesterone level can be used as one of the bases for the early diagnosis of ectopic pregnancy. If hCG alone is not enough to determine the cause, blood progesterone can be observed to assist in the diagnosis. The β-hCG value of a normal intrauterine pregnancy should increase significantly from the 9th to the 11th day, and then double every day, while the hCG metabolism of an ectopic pregnancy is low and the daily increase is small.
