I weight about 107-110 and I'm 13yrs old, am i bit overweight?

I'm just always staring down at my thighs and their bigger than the girls around me, but their taller than me. I haven't weighed myself in awhile, and I quit athletics a while ago. I am 5' ft, and I'm just worried about my weight, last year I weighed 92, and now I gained a bunch of weight and have painful stretch marks. Any help :(??
