help please !!!!;( talk about ib and bleeding 4 days early

So a couple of days ago I had discharge with two drops of brownish pink blood in it, today I started bleeding it's not super heavy but it's enough that I have to change my pad after 6 hours. I always have 28 day cycles plus or minus a day and if this is my period it's 4 days early creating a 24 day cycle which I have NEVER had. Can this be anything else other than my period??? Or am I just out now 😞
