Does it make sense to only grow sometimes?

Hey I am 15 years old and around 5'10 tall, I have noticed that I grew quite well during the last summer that was about 9 months ago, and after that summer I haven't grown that much.. maybe just a little bit. Does that mean that I stopped growing forever? Or is it possible that I'm just not having a growth spurt or anything right now and that I might still have another one this summer or next year? Is it possible that I'm still growing, just inconsistent with my growth spurts?
