Will purging have an effect?

I am on a diet of 800-1000 Cal's a day. Today However I know I went over that with a bacon egg and cheese from dunkin donuts 560 cals, two bags of 100 calorie pop corn, cheese its, turkey sandwich on wheat with american cheese, and brownie fudge ice cream. I am 5 foot 3 inches and weigh 119, but trying to be 112-114. I am not in anyway bulimic, but Im feeling really guilty about today. I was just curious if purging would even have an effect at all. Let me know thanks
