During the process of fertilization of the egg, a small amount of vaginal bleeding may occur. This bleeding is usually very small, some of it is only transient, or there is a brown discharge from the leukorrhea. However, if there is a lot of vaginal bleeding in the early stages of pregnancy, it is not normal and may be due to preterm miscarriage, embryonic dysplasia, bleeding disorders, or gynecological diseases. Therefore, if you experience vaginal bleeding in early pregnancy, you need to go to the hospital for an examination to find out whether the symptoms are caused by physiological factors or diseases.
