What are the causes of vaginal bleeding during pregnancy?

Small amounts of vaginal bleeding during pregnancy put women in a relatively dangerous state during pregnancy. Therefore, when these symptoms appear, many women must pay attention to them to avoid miscarriage and other diseases. The following is a detailed introduction to the causes of small amounts of vaginal bleeding during pregnancy. Women who experience these symptoms can have a comprehensive understanding of them.

Placenta: If the placenta falls off or separates from the endometrium, it will cause bleeding. If the placenta falls off, the fetus will not be able to absorb oxygen and nutrients, and you should seek medical attention as soon as possible.

Mucosa: Mucosa is the red erosion at the vagina or uterine opening. It is also possible that bleeding is caused by external stimulation such as sexual intercourse or gynecological examination.

Cervical canal: When the uterus contracts, secretions will flow out of the cervical canal, sometimes mixed with mucus and blood. The bleeding signs before delivery also come from here.

Polyps: Polyps are small benign bumps formed at the opening of the uterus. The blood that flows out of them sometimes mixes with the secretions from the cervical canal.

The harm of vaginal bleeding in early pregnancy to the fetus

According to statistics, after vaginal bleeding occurs in early pregnancy, about half of the patients can continue to have a successful pregnancy, about another 30% of patients will experience spontaneous abortion, 10% of patients will have ectopic pregnancy, and a very small number of patients may have problems such as hydatidiform mole, cervical lesions, etc. Many studies have shown that if vaginal bleeding occurs in early pregnancy and the pregnancy continues successfully, the proportion of fetuses with congenital abnormalities does not increase.

After understanding the reasons for vaginal bleeding during pregnancy, in order to avoid harm to the fetus, it is best to go to the hospital for a comprehensive examination. After examination, if the fetus is indeed harmed, it is necessary to treat it as soon as possible with the correct method to avoid miscarriage and cause unnecessary serious losses.
