What is the progesterone level during pregnancy

Progesterone plays a major role in female fertility and embryonic development. It stimulates changes in the uterus during pregnancy and promotes successful implantation of the embryo. Low progesterone levels during pregnancy can lead to threatened miscarriage, so it is a major concern for many women who are preparing for pregnancy or are already pregnant. The progesterone level during pregnancy varies according to the number of weeks of pregnancy. The more weeks and months there are, the higher the progesterone content. Older pregnant women are more likely to experience low progesterone levels. When this happens, they should go to the hospital immediately to protect the fetus. Do not take medicine without authorization. Improper use may cause fetal malformations.

Low progesterone levels in women can cause embryonic development to stop and cause miscarriage, which is very harmful. In order to provide the baby with a healthy growth environment, it is important to pay attention to pre-pregnancy checkups and eliminate unfavorable factors before becoming pregnant. You can also adjust progesterone levels through diet, such as eating soy products and fruits rich in pectin such as strawberries, peaches, kiwis, etc. However, the intake from food is very small. Pregnant women still need to go to a regular hospital to protect the fetus and supplement progesterone to ensure the smooth birth of the fetus.
