I have also had this same problem for years now. The spotting is constant, only stopping for about 1 week after my period then starting back up until my next period. My doctor just keeps switching my birth control. He just recently switched me to the patch and said it's usually very effective in women who have this problem. It is very frustrating. My boyfriend is very supportive about it but is also getting a little fed up with it because it affects our sex life. I'm just hopeing the patch will work for me.
