Reason 1: So basically, you’re still kind of in a puberty stage. Stretch marks are a type of growth spurt.
Reason 2: If you have started taking a new medication, you may have that side effect.
Reason 3: If you have been weightlifting, though this may not be true considering most of the time stretch marks come on the stomach, you may have stretch marks for rapid muscle growth.
Hope this helps <3
