early period

ok so I had my period 9 days early then normal and now im having very light cramping and supposed to be ovulation this week but im feeling dry and very little discharge. I have been stressed and worried about something. last month I had my period for 5 days and that was normal but the all of the sudden Aug 2 I stated my period and that was way to early and im supposed to start around 10th but had it early. what the hell is going on am i pregnant or not
