I'm having headaches, unusual cramping, and a dark brown discharge thats lasted from a week before my period, into now which almost the end of what would be my period. I've been extremely emotional, fatigued, and have had a hightened sex drive. I'm sexually active, on the pill, but my partner always pulls out. I have sex regularly, but not since I've gotten these symptoms. Age 17, height 4'11, weight 95 pounds.
