birth control pills

i’m in college now in a dorm w so many girls so i think it made my period come a week before it was supposed to.. anyway so i j was like well i’m j gonna keep taking my pills ( i had one week left of the combination pills and then the next row was the sugar pills which i usually take on my period) so my question is now am i ab to have a period that lasts 2 weeks long??? because now that my period should be over i still have the sugar pills left, and i think my body thinks that since im not taking any pills w hormones that it’s time for my period. even tho i j had it last week … please someone answer this.
