The normal value of progesterone is between 20-30ng/ml and the level of progesterone is related to the time of testing after pregnancy. Progesterone has a protective effect on the fetus, and if a pregnant woman’s progesterone is too low, it may lead to miscarriage, so when progesterone is very low, it is important to go to the hospital and let the doctor check if it can be supplemented. It is common to use medications such as progesterone tablets, but you can also get it from food to regulate it. You can eat foods containing soy isoflavones, which can help the pregnant woman’s body to produce progesterone, and you can also eat fresh fruits such as kiwi and grapefruit. Because progesterone is a dynamic indicator that will keep changing over time, you can’t supplement progesterone privately, as it will not only fail to achieve the effect of fetal preservation, but may also harm the fetus.
