Progesterone level less than 10umol/L at 7 weeks of pregnancy, if the embryo develops normally can continue to keep the fetus. However, if the embryo stops developing, it needs to be cleared in time, but generally speaking, such a progesterone value has a higher probability of poor embryo quality. Women in the early stages of pregnancy, there may be insufficient progesterone secretion, that is, low progesterone levels, but if the embryo develops normally, the progesterone level will rise with the gradual development of the embryo, the woman can also supplement exogenous progesterone such as progesterone to carry on the treatment of fetal preservation. However, if a woman’s progesterone level is less than 10umol/L at 7 weeks’ gestation, and the embryo has stopped developing, there is no significance of fertility preservation, and she needs to be cleared in time, otherwise the embryo in the uterus may cause complications such as disseminated intravascular coagulation. Women with progesterone levels less than 10umol/L at seven weeks of pregnancy are recommended to have regular checkups and be treated under the guidance of a doctor.
