What is the cause of bleeding in the fifth month of pregnancy?

If a small amount of bleeding occurs within five months of pregnancy, it is necessary to check for cervical erosion, cervical polyps, vaginitis, and placenta previa, all of which can cause vaginal bleeding. It is also necessary to observe whether it is accompanied by uterine contractions and abdominal pain symptoms to avoid the possibility of threatened abortion. Gynecological internal examination and B-ultrasound examination can be performed to find out the cause of the disease and treat it accordingly. During the fifth month of pregnancy, you need to pay attention to the diversification of your diet, eat more high-protein foods, eat more fresh fruits and vegetables, appropriately supplement calcium, iron and other vitamins, and have regular prenatal checkups.

If vaginal bleeding occurs during the fifth month of pregnancy, the first thing to consider is threatened abortion, but it depends on the amount of vaginal bleeding and its characteristics. If a small amount of vaginal bleeding occurs, it is usually dark red or bloody leucorrhea, and no pregnancy product is discharged. Then there will be intermittent lower abdominal pain or back pain. During a gynecological examination, the results show that the cervix is ​​not open, the fetal membranes are not ruptured, and the size of the uterus is consistent with the number of weeks of amenorrhea. Generally, this condition can be diagnosed as threatened abortion. In this case, the normal symptoms can disappear after rest and treatment, and you can get pregnant again at this time.

If the amount of vaginal bleeding increases or the pain in the lower abdomen worsens, it may develop into inevitable miscarriage. That is, on the basis of threatened miscarriage, bleeding increases, abdominal pain worsens, or vaginal discharge occurs, which is placental abruption. At this time, the cervix has begun to dilate, and sometimes the embryo tissue or the gestational sac can be seen blocking the internal cervical opening, which is inevitable miscarriage. Therefore, the bleeding should be judged according to the situation to determine whether it is a threatened miscarriage or an inevitable miscarriage.

The possible causes of vaginal bleeding during five and a half months of pregnancy mainly include: 1. Uterine fibroids. Before pregnancy, the patient had already suffered from uterine fibroids, but it was not treated in time or not taken seriously. After pregnancy, the body's female hormones change, the size of uterine fibroids increases, and bleeding occurs. 2. The embryo adhesion site is too low. If the embryo partially or completely covers the internal os of the cervix, the probability of abnormal vaginal bleeding in women will increase relatively with the increase of gestational age. Especially after sexual intercourse, physical activity or the stimulation of sports competitions.

Threatened abortion, vaginal bleeding accompanied by lower abdominal pain, is considered to be caused by threatened abortion. No matter what the cause of vaginal bleeding is, it must be taken seriously and you should go to the hospital for treatment as soon as possible and start treatment after finding out the cause.
