Vaginal Discharge HELP

So i am sexually active but i am on birth control pills and use condoms most of the time (there have been a few times without but we stopped after a few seconds to put on a condom). Today i noticed my discharge was a little on the thicker side and at one point had a slight pink tint to it, not very apparent. It was just off white. My period ended on Sunday (today is Wednesday) and i am on day 8 of my cycle. Does anyone have an idea of what could be going on?
