Is it bad that I ate this much?

Yesterday for breakfast I had two pancakes. Then I went to a party around 330, and I ate a lot! I do not eat a lot normally, sometimes I don't eat enough but it was a party so what can I say.. I had a cheeseburger, two fried chicken wings, an egg roll and a couple mini pretzel nubs. I realize this is a lot, am I going to gain weight? I'm 13 (girl) 5'4 and 127 pounds.
