There are signs of miscarriage, which is manifested by the presence of preeclampsia, mainly a small amount of vaginal bleeding or pain in the lower abdomen, and requires treatment to preserve the fetus. Commonly used drugs are progesterone, and Chinese medicines, such as An Fetus Pill, Pregnacare, as well as vitamin C and vitamin E are available. However, ultrasound examination must be done before fetal preservation to see whether the gestational sac in the uterine cavity is normal, whether there is fetal heart and buds, if there is a cessation of embryonic development, it is not possible to preserve the fetus. If the development of the fetus is relatively normal, you must continue to keep the fetus. If it is early pregnancy, absolute bed rest is not needed, but rest is necessary; if it is in the middle or late stage, bed rest is needed.
