Pre-eclampsia most often occurs during the first trimester of pregnancy, and can occur as early as about thirty days after menopause. Most miscarriages are associated with poor embryonic development. In addition, some pregnant women have low progesterone levels, do not rest well in the early stages of pregnancy, and have poor physical health, which can also increase the probability of miscarriage with preeclampsia. Patients with miscarriage with preeclampsia need fertility preservation treatment, but the success of fertility preservation mainly depends on the vitality of the fetus and whether there is any developmental problem of the fetus. During the period of abortion preservation, we should take a good rest, avoid strenuous exercise and sexual life, and keep a good attitude, if the mood is too nervous, it will also affect the effect of abortion preservation.
