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

Pregnancy that is three months old is considered mid-pregnancy. The main reasons for bleeding are: 1. Symptoms of threatened abortion; 2. The placenta is too low; 3. Hemorrhoidal bleeding or urethral bleeding, mistaken for vaginal bleeding; 4. Cervical erosion or cervical polyp bleeding, often with a history of sexual intercourse. No matter which situation it is, you should go to the hospital as soon as possible, conduct relevant examinations, and start treatment after determining the actual cause. Pregnant women should pay attention to bed rest as much as possible, eat light food, and keep a calm mind.

If a pregnant woman experiences bleeding in the third month of pregnancy, she needs to consider the following conditions: 1. Threatened abortion. Bleeding and abdominal pain before 28 weeks of pregnancy should be considered as threatened abortion. If the bleeding is heavy, miscarriage may be inevitable, and this situation requires tocolysis treatment. 2. Consider the possibility of low-lying placenta or placenta previa. Many pregnant women find that the embryo is located relatively low in the early stages of pregnancy, and the placenta is at or close to the internal os of the cervix, which can easily cause painless vaginal bleeding. Later, as the month progresses, the position of the embryo may move up, but if bleeding occurs, surgical treatment is required.

This type of situation should be taken seriously, as it may be due to the incomplete development of the test tube embryo itself, exposure to an unfavorable living environment during pregnancy, such as radioactive substances, or taking some therapeutic drugs, which may cause abnormal development of the test tube embryo or baby, stimulate uterine contractions and cause vaginal bleeding. Secondly, bleeding is caused by estrogen deficiency or personal illness. Secondly, if a pregnant woman has cervical erosion, it may cause more or less bleeding throughout the pregnancy. Therefore, pregnant women are advised to do various examinations on time to ensure the healthy growth and development of the fetus.

If vaginal bleeding occurs during pregnancy, you must go to the hospital for a color Doppler ultrasound examination immediately. It needs to be taken seriously. Vaginal bleeding should not occur during a normal pregnancy because menstruation has already stopped. Vaginal bleeding indicates that there is a problem of uterine bleeding. Ultrasound is needed to check whether there is a liquid shadow around the gestational sac, assess the amount of bleeding and whether there is a possibility of further bleeding. Reduce the amount of exercise and rest in bed if necessary, test the progesterone level, inject lutein copper, and treat the fetus.
