After two months of pregnancy, if you have not yet reached the third trimester, you still need to be careful to check your progesterone regularly. Generally speaking, 8-10 weeks of menopause is a transitional period for pregnant women, and the placenta is formed when pregnancy reaches the third trimester, at which time the fetus can take in nutrients completely through the placenta. In the first trimester, because the placenta is not fully formed, the development of the embryo needs sufficient estrogen and progesterone in the pregnant woman’s body to maintain. Therefore, after two months of pregnancy, if the pregnant woman has not yet reached the third month, or need to pay attention to regular checks on the value of progesterone, if the progesterone is relatively low, do not rule out the possibility of preterm miscarriage. Pregnant women in the early stages of pregnancy should pay attention to rest, avoid strenuous exercise, pay attention to develop good dietary habits, do not stay up late, regular checkups, abdominal pain or abnormal vaginal bleeding and other conditions as soon as possible to seek medical attention.
