How many days does menstruation last during pregnancy

The characteristics of pregnancy menstruation are less bleeding, lighter color, and shorter duration. Generally speaking, the amount of bleeding is not large. So, how many days can pregnancy menstruation last?

Pregnancy menstruation, as the name implies, is menstruation during pregnancy. But pregnancy menstruation is not a normal physiological period "menstruation", which means that there will be a small amount of bleeding in the first three months of pregnancy. Many women do not know that they are pregnant because they are pregnant.

There may be a small amount of bleeding during the implantation of the fertilized egg, which generally does not last more than 3 days. There is generally no vaginal bleeding during pregnancy, otherwise the possibility of threatened abortion and ectopic pregnancy needs to be considered.

Modern medicine believes that the human chorionic gonadotropin produced by pregnant women cannot transform the corpus luteum of the ovary into the corpus luteum of pregnancy, and the ovarian function continues to be active, resulting in a small amount of vaginal bleeding every month. After 3-4 months of pregnancy, the placenta secretions replace the ovarian function. Cyclic bleeding will no longer exist.

Women will not have menstruation after pregnancy. However, some women still have vaginal bleeding on the next menstrual date after pregnancy. At this time, pregnant women often mistake it for menstruation, so they don't know they are pregnant. This situation is called "pregnancy menstruation" after women become pregnant.
