If i always have a brown discharge during "period" (no red) while taking birth control for many months, did birth control pill fail me?

That depends: If you are taking pills straight through, you should eventually stop spotting. If you haven't, then try a new pill for 3 months to see if the breakthrough bleeding will stop. If you are leaving 5-7 days between you last active pill ; the next pack, your period can be very slight as what pills do is prevent your body from producing a uterine lining. Little lining, little period.No preg, no fail!

No.: No, it isn't a sign of 'failing', but. The birth control pills can definitely change the type, color, amount of bleeding that a woman has during her menses. Sometimes the 'period' becomes very light (sometimes the pills will cause menses to stop, which is an effect of the progestin hormone in the pills, and the type and amount of estrogen), or can become discharge, as you described.
