Healthy weight for me...? I'm 13 years, very muscular girl. Do I need to gain some or lose some?

Hi, I am a 13 year old girl and I'm 5'1. I weigh 88-89 pounds. Is this too heavy? I'm certainly not skinny or fat, I am actually very muscular and can do 100 push-ups, squats, etcetera. Do I need to gain more weight or lose some, or is this weight ideal? Thank you.
