It is not possible to determine how long the abdominal pain will last with a preeclampsia, but it usually improves after the preeclampsia improves or the miscarriage is complete. Pre-eclampsia often manifests as paroxysmal lower abdominal pain, there may be a small amount of vaginal bleeding, the mouth of the uterus is closed, there is no discharge of the pregnancy, and ultrasound shows that the embryo is alive. Patients with symptoms of preeclampsia are advised to rest and be treated with progesterone or dextroprogesterone. There are two outcomes of preeclamptic miscarriage, i.e. improvement and miscarriage. If the abdominal pain gradually improves and the vaginal bleeding decreases, the pregnancy can continue in most patients, but there may be increased abdominal pain, vaginal bleeding, and even expulsion of the pregnancy, and after complete expulsion of the pregnancy, the abdominal pain may be relieved and the vaginal bleeding may decrease. Patients with symptoms of preeclampsia should consult a doctor promptly and follow medical advice.
