6 days late

Soooo 6 days late.... Taking a test on friday, so far ive had tender breast, constipation (TMI) Im peeing all the goddamn time - all my periods are irregular so i have no clue if its even past my period or not. I had some light spotting on the day my period was supposed to come but that was is. My back hurts, im exhausted... what do you guys think? Could i be pregnant????
