What symptom does 3 months 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 late pregnancy or labor after the lower uterine segment gradually extended, cervical canal disappeared, or cervical dilatation, and attached to the lower uterine segment or the mouth of the cervix of the placenta can not be extended accordingly, resulting in the placenta previa part of the detachment from its attachment, so that the blood sinus rupture 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. The first bleeding time of complete placenta previa is often early, about 28 weeks of gestation, the number of repeated bleeding is frequent, the amount is more, sometimes a large amount of bleeding can make the patient into a state of shock; Borderline placenta previa occurred later in the first time, mostly at 37-40 weeks of gestation or after labor; The first bleeding time and bleeding volume of partial placenta previa were between the above two. In patients with partial or marginal placenta previa, rupture of membranes is conducive to the compression of fetal presentation on the placenta. If fetal presentation can drop rapidly after rupture of membranes, it will directly compress the placenta and stop bleeding. Due to repeated or massive vaginal bleeding, anemia may occur in patients. The degree of anemia is directly proportional to the amount of bleeding. Severe bleeding may lead to shock, fetal hypoxia, distress, and even death.
