1. Threatened abortion

Irregular or excessive uterine contractions during pregnancy can also cause vaginal bleeding. It may be caused by fetal chromosomal abnormalities, maternal hormone disorders, congenital uterine developmental abnormalities or acquired defects, immune system problems, viral infections, chronic diseases of pregnant women, overwork, excessive stress, too intense sexual life, environmental pollution, improper use of medication, smoking, drinking, excessive caffeine intake, etc.

2. Ectopic pregnancy

If a woman has had fallopian tube surgery, has had an ectopic pregnancy, or has had pelvic inflammation, it is very likely to cause an ectopic pregnancy. This is because the wall of the fallopian tube is relatively thin, and the gradual development of the fertilized egg will cause it to expand, causing the wall to rupture, then abnormal vaginal bleeding will occur at 7 to 8 weeks of pregnancy. Sometimes it may also lead to shock due to severe abdominal pain or heavy bleeding in the abdomen. Therefore, women should diagnose the possibility of ectopic pregnancy through examination in the early stages of pregnancy and take effective measures in a timely manner.

3. Cervical lesions

If a woman has poor sexual hygiene habits, irregular lifestyle, or poor body resistance, it may cause cervical disease, resulting in early pregnancy bleeding. If the uterus is inflamed, it may cause cervical erosion, or if you already have uterine polyps, it is very easy for the surface capillaries to rupture and bleed due to hormonal changes after pregnancy. Therefore, if a woman has vaginal bleeding in the early stages of pregnancy, she should go to a regular professional hospital to check whether there is any problem with the cervix.

4. Premature birth

If a woman is younger than 18 or older than 38 when she becomes pregnant, if she has certain diseases, is under too much stress, has a history of premature birth, has multiple births, has uterine fibroids, a bicornuate uterus, etc., she should go to a regular professional hospital for diagnosis and treatment in time.
