pregnant or period symptoms?

Delanie
I'm not sure if i'm just siking myself out but..
my boyfriend and i never use condoms instead the pull out method which has always worked. i am on the pill and am pretty okay about taking them on time. earlier this week it was odd because i experienced light bleeding and cramping but it wasn't my period. (this has never happened before). it lasted for about 3 days and i also believe i've been bloated the past 2 days. i start my last row (period row) tomorrow. am i pregnant? or is this normal?
