What happens when you take 2 excedrins and ibuproben 800 within 30 minutes prior to taking children's motrin?

I took Children's Motrin (chewy tablets) and Ibuprophen 200mg at two o'clock this morning. then around an hour and a half ago I go to school and take 2 excedrins and an Ibuprophen in less than half a hour away from each other. Should I be worried? should I have side affects? what should I do?
