Break through bleeding on Loestrin.
So, I've been on Loestrin for about a year and a couple of months. My boyfriend and I are sexually active and don't use condoms. My periods each month have been normal, nothing seemed weird. But my last 2 periods I've started having brown/small red discharge about a week after my period ends. I'm not sure if it's just break through, or what? Or maybe it's just that I need to switch pills? Help please, I'd love some insight!
