I think this girl likes me but im not sure?

i just met this girl during p.e and she is pretty attractive... she is blond and kind of shorter than me and she got some weights on her chest. anyway i was sitting on the bleachers around the track cause i got in trouble and the girl was walking around the track and every time she passes by me she kinda looked at me and walked away and once she told me she liked the hat i was wearing. and the period was over...... do u think she has any interest in me???? cause i think she is pretty nice and i would like to go out with her...
