Yeah!
When I was around 12, I was really pudgy and short, and then around the time I turned 14, I grew about four inches and got thinner.
Even if you think you look fat now, which you do not at all omg you look great, once you grow more, your body weight evens out. c:
Put please don't worry about losing weight, you're adorable!
Just focus on making sure you're geting good nutrients, and sleeping enough. xD
