bad period or what?

Past like three days I had really bad headaches and I've been really irritable and moody also breaking out like the acne that hurts and is under the skin and I start my period after tomorrow it's weird to me because I never break out before periods and I never had these pimples like that those bad ones so many in a short period of time, also yesterday and today I been spotting light pink and some brown.  I stay mad like all the time too!😩 is it just a bad period that's about to come or something else?
