In October, she was pregnant, and the expectant mother was very hard. She looked forward to the baby’s bring, but also worried about some accidents during pregnancy.After finally spending the early and second trimester of pregnancy, it was about to be produced immediately, and the vaginal bleeding occurred.The following situations are common in vaginal bleeding in the third trimester (after 28 weeks of pregnancy).
1. During delivery
24-48 hours before childbirth, the mature uterine section and the cervix were forced to expand, resulting in the separation of the fetal membrane and the uterine wall attached to the cervical mouth. A small amount of blood broke the capillaries, which is commonly known as "seeing red".This is the case where pregnant women who are close to the due date indicate that they are about to give birth soon, and they should be happy to see the baby immediately.
2. Early peeling of placenta
Early peeling of placenta is related to hypertension, chronic hypertension, chronic nephritis, short umbilical cords, and decreased uterine pressure. Bleeding is also accompanied by abdominal pain.The blood vessels at the placenta attachment are ruptured, and there will be hematoma between the placenta and the uterus. When the blood is accumulated to a certain degree, there will be vaginal hemorrhage. If the placenta attachment is high, the blood cannot flow out, and the contraction will occur.Once the placenta is peeled early and did not treat it in time, the fetal death palace and pregnant women bleeding will occur.
Third, placenta front
Under normal circumstances, the placenta should be attached to the front, back, left, and right wall of the uterine cavity, but if the endometrium of the pregnant woman in the early pregnancy is relatively thin, the embryo does not grow and develop in the normal position of the uterine cavity, but is close to the position of the cervix.Growth and development, then the placenta of the third trimester will become a front placenta.In addition, the uterus has inflammation, tumor, deformity, etc., and the placenta prefix will also appear.
With the growth of pregnancy time, the lower section of the uterus slowly stretchs, the uterine mouth gradually opens, and some placenta will be dislocated and divergent with the uterine wall, which will bleed.However, this bleeding phenomenon usually does not have abdominal pain, and the initial amount is very small, but there will be more and more in the future. Generally, pregnancy needs to be terminated in advance.
How to judge severity
If the amount of bleeding is small and near the due date, then you can consider that it is about to produce and prepare for production.If the amount of bleeding is large, you need to consider that the placenta is peeled early or the placenta is topped. At this time, you need to go to the hospital for examination as soon as possible to prevent hair accidents.
