About a week after my period ended I started getting a bloody/brown discharge. It's very light and its not happening all the time but it's starting to worry me. It's been going on and off for about a week now and has started going white, sometimes brown. My period is due in a week. I'm on a contraceptive pill and had sex in the week straight after my period. Please help!'

I've also been stressed to the max and haven't been sleeping. I'm afraid to say anything to anyone in case it's something bad.
