I am just shy of 5'3" and know that you are just right. When I was your age I was around 105 and was too skinny. Continue to eat right and get regular exercise and you will have a good chance of keeping yourself at a very good weight.
I'd say probably neither............5'2 is not a bad height to be. Below is a small bit from a height/weight chart. So depending on your frame size, you could weigh anywhere from 108 - 143.......
Height Small Frame Medium Frame Large Frame
5'2" 108-121 118-132 128-143
If you eat well and get plenty of exercise, so you aren't getting flabby, you are about right........
