I have had brown spotting for about 5 years now, but I have a normal period every month. For about a week after my period I have no spotting, but after that I have constant brown spotting until my next period. I have told my doctor about this and he doesn't really even acknowledge it. I was going to the health clinic when I first started experiencing this and they would keep changing my birth control pills to see if it helped and it didn't. I have gone off the pill for years and that didn't help either. Also just thought that I would mention that I get a lot of headaches, I am tired a lot and I have a lowe sex drive in case it could be connected.
