Are these stretch marks?

SLSYW15
I don't know if they're stretch marks or something. So, if they are stretch marks, can you guys please tell me how to make them disappear? I can't wear shorts because they're appearing on my calves, my thighs and my butt. I'm really having lack self-confidence because of these unknown little red lines. I'm just 13 and not obese.
