Pregnant !?

I've been on birthcontrol for about 3 months now, i've been taking my pills everyday, only skipped one day i forgot but took 2 the next day. On friday my boyfriend came in me, i started my sugar pills monday for the first time, i've previously skipped them and started a new pack but ihaven't  gotten my period, i have been bleeding lightly since Nov. 12ish  and now that im taking my sugar pills i only see blood everytime i wipe, i am having a slight pain like cramps on my right side, like my ovary is hurting
