Increasing Calorie Intake...Now or Wait

I can't figure out/decide when I should increase my calorie intake. I am 5'2.5" tall and weigh 124.5 pounds. My goal weight is 110. I have been eating 1200 calories for several months. My weight loss has slowed and I am thinking I might need to try increasing my calories to 1300. I plan on eating any and everything I want on Thanksgiving but really really really do not want to ever see a number greater than 125 on the scales ever again. So should I wait until after Thanksgiving to increase my calories (with the hopes of getting off a bit more weight before throwing eating caution to the wind) or go ahead and do it now? Or should I drop my calories instead of increasing them? I want this weight loss to continue and to hit my goal weight!
