In the sixth month of pregnancy, it is recommended to visit the hospital if there is brown blood coming out. If there is bleeding, accompanied by stomach pain and hardness, it is also possible that a pre-eclampsia has occurred. If there is only bleeding and no stomach pain, it is possible that there is placenta praevia or a gynecological inflammatory infection. For example, cervicitis or erosion of the cervix can cause brown blood. You should go to the hospital for examination to determine the condition and then take symptomatic treatment. If the miscarriage is caused by pre-eclampsia, you need to pay attention to bed rest, do not exercise strenuously, also need to pay attention to maintain a relaxed mood, do not be too nervous, otherwise it will easily lead to uterine contractions, leading to an increase in the chances of preterm delivery.
