help πŸ˜…πŸ™ƒπŸ˜Ά period question

So I've been on birth control pills for 5 months now, I'm usually pretty good about taking them at the same time everyday.. but this last month I got my period super early, not even 2 weeks after my last. It wasn't very heavy at all, and I stopped after a couple days. But now I've got some brown discharge that comes and goes throughout the day. If it were my period, it would be blood by now...it's also starting to itch and become uncomfortable. Any girls that have had something similar?? Or have gone through this?? If it were a yeast infection wouldn't It be white??Β
