Well here goes this long story.. lol.. me and my fiancée has been trying to conceive for about 2 years now.. my AF has been very regular.. my period was suppose to start on the 2nd of this month, but it didn't start until a couple of days later... when it did start, it was very very light... then just last night, it got really heavy like one of my regular periods would... I really want to be pregnant... my period has never done that before.. I just want to the chances that I am pregnant or what's going on... help

Your period was probably just a couple days off. If you think you might be pregnant though take a pregnancy test.
