Hey, I'm 15 I currently weigh 158lbs a week ago I weighed 165lbs. I have done anything that's not normaly, last weekend I had 4 hockey games in 3 days for a tournament and past Wednesday and thursdays I had 3 games total. I also drank last weekend and I drank twice this weekend, if anything I would have thought to stay normal weight or gain a little. So what I'm asking is if this is normal.
