Hi, there are several ways to understand if the bleeding is normal or not. The most recommended way is to go to your gynecologist and perform an examination of the uterus and cervix with biopsies, that way you can understand if the lining of the uterus is normal or if there is something that is causing the bleeding such as a fibroid or a tumor. Secondly, you can try to perform hormonal treatment such as birth control pills and see if the bleeding depends on hormones or not, but for this you should also consult the gynecologist. Did you go to the gynecologist for a checkup?
