Will i be this body shape forever?!?

So i am a 14 years old girl and Iam about 160cm and 65kg. I am nto fat, not skinny, just a bit over average. I excersie and eat well and I'm not really seeing much results. I've only started really caring about my weight at the end of last year and was wondering will I be like this forever or will my body shape change? I don't really have a waist and I'm hoping that might change?!
