Pregnant women bleeding is often vaginal bleeding, it is not possible to directly determine whether labor is imminent or not, but needs to be judged according to the bleeding time, common cases are as follows: 1. Bleeding in early pregnancy, suggesting possible preterm abortion or ectopic pregnancy. If vaginal bleeding occurs before 28 weeks of pregnancy with paroxysmal abdominal pain or low back pain, consider pre-eclampsia miscarriage and need to carry out fetal preservation treatment. If there is soreness and hidden pain on one side of the abdomen with a small amount of bleeding, or acute severe abdominal pain with heavy vaginal bleeding, ectopic pregnancy is considered and requires hospitalization. 2. If bleeding occurs at 28-37 weeks of gestation, there is a possibility of preterm labor. If the examination shows that the fetal membranes are intact, try to keep the fetus until 34 weeks if the condition of the mother and child allows, and apply drugs under the guidance of the doctor to control contractions. If the fetus is less than 35 weeks and delivery is possible within 1 week, glucocorticoids should be used under medical supervision to promote fetal lung maturation. If the fetal membranes rupture prematurely or the vaginal discharge is abnormal, the infection should be actively controlled and the treatment of preterm labor should be stopped at the right time; 3. Late pregnancy bleeding mostly represents prodromal labor, generally speaking, after bleeding, you need to keep a lying position, be ready to deliver at any time and go to the hospital for delivery in time. If the bleeding is more, even more than the amount of menstruation, there will be the possibility of placenta praevia or placenta abruptio, and you need to seek medical attention in time. It is recommended that pregnant women should not be overly nervous, pay attention to a light diet, get enough sleep and exercise properly. If there is bleeding, abdominal pain with abnormal fetal movement or regular contractions, seek medical attention in time.
