Been spotting on and off for the past month. been on pill for 1+ year, have never had breakthrough bleeding this long?

Options: Have you tried taking your pill twice daily for 5 to 10 days to stop the breakthrough bleed (btb)? If it's a persistent problem, it may be time to switch to a pill with a higher estrogen content (not sure which one you are on) to stabilize the lining of your uterus. Speak with your doctor and devise a plan together. He or she may also want to see you in the office for this problem. Good luck!
