If i have overeaten and then throw up afterward, will I gain weight?

I work out four times a week, running for more than 7 kgs a time. I strict my calories intake around 1600-1700 in order to maintain my current weight, which is 54kgs (my height is 172 cm). However, I am very obsessed with counting the calories. I could control myself from overeating no more than two week and when it comes to the end of first week or second week, then i binge! I binge on cakes, junk food .. all those high products u could think of. However, after i overeat I just throw up (I make myself sick). Will this make me gain weight? Just now i just overate and it has been just six days from the last time i binged (but i threw up afterwards anyway), will this make me fat or gain weight?
