I am on the contraceptive pill, which I always take daily and have been on it for about a year and a half now. Me and my partner are sexually active and do not use other contraception as we are in a steady relationship and live together. Yesterday afternoon I noticed a browny discharge and had cramping the day before . It is still there today but has started changing colour going more red. Its extremely light only noticeable when wipe there. My period is not due for another 4 days and due to being on the pill it is exact, never early or late. Ive never experienced this before, very unusual for my body. Just wondered if anyone knew why or what this is?
