1. Overwork. Pregnant women in the early stages of pregnancy are overtired or engaged in heavy physical work, and the physical and psychological pressure is too great, which can easily cause vaginal bleeding in pregnant women.

2. Physiological bleeding. After a woman successfully conceives, some women will still experience a small amount of vaginal bleeding during menstruation. This is just a physiological reaction and does not require treatment.

3. Abortion. Before the placenta is fully developed, the implantation of the embryo is not yet stable, and pregnant women are prone to miscarriage at this stage. When a miscarriage occurs, the embryo and the uterine wall of the pregnant woman will separate to varying degrees. When the blood vessels on the separation surface rupture, the uterus contracts, which will cause the symptoms of vaginal bleeding in the pregnant woman.

4. Ectopic pregnancy. The wall of the fallopian tube in women is relatively thin. When the fertilized egg develops to a certain extent, the wall of the fallopian tube expands and ruptures, resulting in abnormal vaginal bleeding. This type of bleeding can easily cause fainting, shock or severe abdominal pain in pregnant women. If treatment is not received in time, it may threaten the life of the pregnant woman.

5. Hydatidiform mole. A molar abortion manifests as small, intermittent bleeding, and sometimes repeated, heavy bleeding.

6. Uterine diseases. If a woman suffers from uterine diseases, such as cervical polyps, cervical erosion, cervical lesions, etc., the changes in hormones after pregnancy will cause the capillaries on the surface to rupture, resulting in vaginal bleeding.

In order to prevent bleeding during the first month of pregnancy, pregnant women must develop good living habits and a regular schedule. It is best to ensure 8 hours of sleep a day and exercise appropriately. Pregnant women should wear loose-fitting clothing, loose belts, and wear flat shoes. You should develop the habit of regular bowel movements and eat more fiber-rich foods to keep your bowel movements smooth. You should bathe frequently and change underwear frequently, but it is not suitable to bathe or swim in the tub. Be careful not to catch cold when bathing. Pay special attention to the cleanliness of the vulva. You can wash the vulva with clean warm water every night to prevent bacterial infection.
