Do I look 180 lbs?

I'm 5'5 1/2", 15 years old, and I weigh 180 pounds. my mom always says I hide my weight well. but I wanted to see if other people think the same. yes, I know I'm overweight. in fact Im on a swim team and have practice for 2 hours 6 days a week. I can just never seem to lose the pounds. :((
