my period is always regular. my period came on march 21st, 3 days early i thought it was real strange. it off on the 25th and came back on the 31st ad lasted 5 more days. my stomach is real sore like i have been excercising, and after the second cycle went off i started having the same cramps i get when im about to get my period. im also having a lil pain in my abdomen area. my stomach also feels a lil hard. could i be pregnant or is it just my body going through some kind of transformation.
