Weird symptoms before period 😱

So I'm supposed to get my period in a day but I'm having really weird things happen to me or at least I think they're weird lol I have white thick vaginal discharge which I know can be an infection, and when I went to the restroom and whipped myself there was some blood very light so I put a pad on thinking it could be my period but I have been bleeding? What could this be maybe a pregnancy? Or just something else
