Help! So confused

So this morning I had a small amount of blood, it was faded but it was definitely red/brown.. Would this be the start of my period or could it be spotting? And if it lasts more than a couple hours it isn't spotting correct? Just so confused, I feel so pregnant. Boobs are killing me as we speak..
