The value of progesterone at 8 weeks of pregnancy is usually between 64.6~113.8umol/l. The normal value of progesterone level in 8 weeks of pregnancy is generally between 64.6~113.8umol/l, if it is lower than the lowest value, it generally suggests luteal insufficiency. Luteal insufficiency will cause low progesterone level, which is not conducive to the growth and development of the embryo, and needs to be synchronized with the level of blood HCG value, as well as the development of fetal heart and buds to clarify the health of the fetus. For low progesterone levels, it is recommended that pregnant women take progesterone supplementation medications, such as progesterone capsules, under the guidance of a specialist when necessary. In addition, the above drugs have certain risks, pregnant women should not take drugs during pregnancy, and must get the guidance of a specialist to avoid affecting the growth and development of the fetus.
