Please help me. Birth control????

Amy
Ok so periods don't agree with me very well. I have prom April 28th and am supposed to be on my period that day. I'm on birth control (not to prevent pregnancy) and this is my 2nd pack. Today I'm supposed to be starting to take week 3 Sunday pill, but I have a plan to get my period a week early, do you think my plan will work? Here it is. Ok so, I didn't take today's pill and I won't for the next 5 days. Hopefully, the stop of pills will make me have my period, (I think?) and if it does, after 5 days of period I will start taking birth control again, starting on the Saturday pill. Then for the next week (prom on Friday) I will take the pills meant for this week. Will this work??? Basically I'm not taking pills this week in hopes this will trigger a period, and then I'll take this week's active pills next week to prevent me having my period again. I'm pretty sure my pills are monophasic, but not 100% sure. Please help me I'm wearing a white dress to prom and can't wear tampons!!!!
