Serious question...

{brandie ♡ rose}
Okay ladies I just had my "period" very light very short. (3 days I stead of 5) I tested 3 days before, and it was negative. But now I'm having weird symptoms, nausea, sore boob, bloating, break outs, and crying outbursts! It's ridiculous the things I cry about now a days. Could I be pregnant even though I had my period?
