If spontaneous abortion occurs in the second month of pregnancy, it will first manifest as a small amount of vaginal bleeding, or slight pain in the lower abdomen. Because the pregnancy reaction is more serious at this time, if the pregnancy reaction suddenly reduces and disappears, and at the same time manifests as pain in the lower abdomen, it may be that the embryo stops developing, and we should go to the hospital as soon as possible to do an ultrasound, and if we can’t see the fetal heart and buds, then it is the embryo that stops growing, and we need to carry out the treatment of removing the uterus immediately. If there is a small amount of vaginal bleeding, and the fetal heart and buds are good when doing an ultrasound, you can apply medication to preserve the fetus, and commonly used medications for preserving the fetus include progesterone and proprietary Chinese medicines. If fetal preservation is successful, the bleeding will stop and there will be no abdominal pain. If the condition continues to develop, there will be heavy bleeding and severe lower abdominal pain, then it is inevitable miscarriage, and the uterus should be cleared as early as possible to avoid hemorrhage.
