What is the cause of bleeding in 37 weeks of pregnancy?

When a pregnant woman reaches 37 weeks of pregnancy, it is already a critical stage. At this time, the fetus has been fully developed and is about to be born, born from the mother's body to meet the challenges of a new life. However, the 37th week of pregnancy is also a relatively dangerous stage. The fetus at this time is easily affected by adverse external influences, resulting in developmental abnormalities and causing damage to the mother's health. For example, why does a pregnant woman bleed at 37 weeks?

What is the cause of bleeding at 37 weeks of pregnancy?

1. Miscarriage: If the amount of bleeding is more than menstruation and is accompanied by severe abdominal pain, miscarriage is bound to occur and further treatment is required. Especially if you experience bleeding symptoms in early pregnancy, it is very necessary to see a doctor.

2. Ectopic pregnancy: When an ectopic pregnancy occurs, vaginal bleeding usually occurs about 40 days after amenorrhea, often accompanied by dull pain, bloating, and heaviness in the lower abdomen. At this time, a urine pregnancy test may be positive, but an ultrasound examination will not reveal the embryonic sac of pregnancy in the uterine cavity. Abnormal tumors and infections can often be found in the fallopian tube. A small amount of vaginal bleeding may also be caused by vaginal infection or sexually transmitted infection, which can cause the vagina and cervix to become infected and inflamed. The inflamed tissue will cause a small amount of bleeding after a cervical smear test, vaginal examination or sexual intercourse.

3. Hydatidiform mole: Hydatidiform mole is a type of deformed fetus. Vaginal bleeding in hydatidiform mole occurs later than in miscarriage and ectopic pregnancy, usually around 3 months. Problems with the placenta or premature birth. If a pregnant woman experiences vaginal bleeding or a small amount of bleeding during the second or third trimester, it may be a sign of a more serious condition. Such as placenta previa, placental abruption (the placenta separates from the uterine wall before the baby is delivered), late miscarriage (before 13 to 28 weeks of pregnancy), or premature birth (before 28 to 37 weeks of pregnancy).

4. Cervical erosion: Cervical erosion may cause more or less continuous bleeding throughout the pregnancy. This bleeding is different from the bleeding caused by uterine contractions during spontaneous abortion, which causes the placenta to separate from the uterus. It will not directly affect the development of the fetus. As long as the bleeding is stopped in time, the pregnancy can still progress normally. If the bleeding is not stopped in time, it will affect normal pregnancy and eventually lead to miscarriage.
