Am I overweight?

I am a 14 year old girl who is 5'4 and weighs 63 kg. my waist measurement is about 32" I think. I am not on any sports teams because I'm too embarrassed to join but I try to excercise at home. I normally do every mon-wed for about 20-40 mins and some times Thursday and Saturday. Even though I do this I get average/ below average on bleep test in school and I am embarrassed about my weight. I also can never seem to loose weight but only gain it. Any ideas on ways to loose weight? Thanks
