Miscarriage in the third trimester of pregnancy is mainly characterized by vaginal bleeding and lower abdominal pain after menopause. The embryo is mostly dead before expulsion, accompanied by hemorrhage of the underlying meconium, necrosis of the surrounding tissues, causing uterine contractions followed by expulsion of the pregnancy tissue, and a small amount of incomplete expulsion or complete failure to expel may result in more bleeding. Miscarriages with abruption, or miscarriages with germination, are characterized by vaginal bleeding followed by expulsion of the tissue, which is accompanied by paroxysms of pain in the lower abdomen or lower back pain. Once this tissue is expelled, the uterus contracts, the blood sinuses close, and the bleeding stops. If at the beginning there is a small amount of vaginal bleeding, dark red or bloody leukorrhea with no tissue expulsion. You can rest and then treat the symptoms, and if these symptoms disappear you can continue the pregnancy. If the amount of vaginal bleeding increases to reach menstrual regulation, or if the pain in the lower abdomen increases, it may develop into an inevitable miscarriage, tissue discharge, etc. are possible.
