I believe that bleeding is not normal. Wearing a device to prevent leaking blood everywhere is just not right sounding to me no matter how you put it! Yes you can lose it the unhealthy way and then it is not good but I have heard of women who lost it the healthy way and still ovulate and have children normally. If you eat and live SAD and lose it, yes that is clearly dangerous. When I eat optimally mine is now hardly noticible and I bet if I were to thouroughly detox I would not have to bother with it at all. We shall see.
