I feel kinda like a pig, will I gain weight?

Ok so I am 14 years old, and 5"2 and weigh 112 pounds. I usually have a great diet and eat everything healthy -no sweets whatsoever, maybe occasionly, but i would consume 900-1100 calories a day. It was perfect and I have been doing that for a long time. Today, for some weird reason I had a horrible sweet tooth. So I just thought I would cave in.. and I had 3 1/2 sugar cookies (190 calories each).. then before that for breakfast I had 1 egg, then later as a snack I had a 90 calorie pack and a 100 calorie bar. THEN I had another granola bar that was high on fiber and was 140 calories. THEN I had a 200 calorie pop tart! THEN a cup of those chips that are with salsa.. 0 trans fat. The brand starts wtih a T.. i forgot what brand. Then for dinner I had 300 calorie Progresso Soup. So i was just wondering, did this big indulgement cause me a pound? Oh and I worked out.. not much because it was crappy outside, I burned 150 calories. please answer, I feel horrible.
