What symptom can placenta previa have?

In late pregnancy or labor, the main symptom of placenta previa is the occurrence of painless recurrent vaginal bleeding without inducement, which occasionally occurs around 20 weeks of pregnancy. Bleeding is due to the gradual extension of the lower uterine segment in late pregnancy or after labor,

When the cervical canal disappears or the cervix is dilated, the placenta attached to the lower part of the uterus or the inner mouth of the cervix can not be extended correspondingly, which leads to the separation of the placenta from its attachment and the rupture of the blood sinus and bleeding.

The amount of bleeding for the first time is generally not much. After the blood coagulation at the dissection site, the bleeding can be temporarily stopped. Occasionally, there are cases with large amount of bleeding for the first time. With the continuous extension of the lower uterine segment, bleeding often occurs repeatedly, and the amount of bleeding is also increasing. The time of vaginal bleeding, the frequency of recurrence and the amount of bleeding are closely related to the type of placenta previa.
