Need help, lost control and binged!?

I have been on weight watchers for two weeks and today I weighed in with not losing anything today for this week; however, today I lost control and binged. I ate my normal breakfast this morning-oatmeal- but for lunch I ate like half a batch of cookie dough and dinner I had like 5 pieces of homemade cheese pizza. Everyday the past two weeks I was eating 1100 calories and exercising 5 days each week. Will this binge hurt my results at the end of the week if I go back to my normal calorie intake of 1100? Please help! I need advice. I was about to purge it out but knew that was the wrong thing to do but I feel so awful and guilty. Serious answers only please!
