Did I reach my growth spurt yet?

I am 14 years old, and I just turned 14 about 5 months ago. I am male. I am going into high school for my first year (9th grade) and I am about 5'3, and most of my friends are taller than me. Everyday I workout, and I almost have a six pack, and I also consume calcium products and vitamins. I usually go to sleep at about 3 or 4 AM because its summer. Did I reach my growth spurt yet ? Is there anyway to grow taller ?
