After pregnancy, in addition to undergoing all necessary examinations, pregnant women should also pay attention to the data obtained from these tests, especially in the early stages of pregnancy. The progesterone level should be monitored as it directly affects the health of the fetus. If the level is too low, there may be a risk of miscarriage. So, how much progesterone is considered normal for pregnant women?
Progesterone shows an upward trend throughout pregnancy, and its reference value also increases with the length of pregnancy. Normally, progesterone levels range from 32.6 to 139.9 nmol/L between 7-13 weeks of pregnancy. By 14-37 weeks of pregnancy, progesterone levels increase to 62.0 to 262.4 nmol/L, and then by 37 to 42 weeks of pregnancy, progesterone levels also rise to 206.7 to 728.2 nmol/L.
The hypothalamic pituitary gonadal axis has a regulatory effect on progesterone, which can affect the physical and nutritional status of pregnant women. If the physical condition is good, progesterone levels will increase. Furthermore, the value of progesterone is also related to the liver and kidneys. If the liver is inactivated more, it can lead to a decrease in progesterone, and even lower than the normal value.
Usually, progesterone testing is more common in early pregnancy, but if the pregnancy is short and the progesterone value is low, it is normal. If pregnant women do not have vaginal bleeding or obvious abdominal pain, it is not recommended to test progesterone to avoid unnecessary troubles. If progesterone is low, it is recommended to adjust the diet by eating foods rich in progesterone, such as soybeans or natural vitamin E, which can improve the condition of low progesterone.
