In women, bleeding problems are commonly noticed across periods. You might notice a slight increase in your period or a very heavy period with intense bleeding. This is because your platelets are lower than usual or not functioning as they should. Thus, when you have your periods, your blood does not form clots in the uterus, and it keeps on bleeding for a longer time.
Heavy periods are common in hormonal problems, and they are very frequent in young women before they give birth for the first time. Thus, even though this is a symptom of leukemia, your doctor will rule out other common causes before starting to think about blood cancer.
