I'm a 15 year old girl and 5'0 in height, will I still grow taller?

Hi, I would like to ask a question. Hopefully there isn't no rude or insulting comments from you guys. I know I asked this question already but I need your help.

I am probably joining a modeling agency this year and as you all know I am 5'0 and I hope to grow around 5'4-5'6 at least. And I am, as much as it pains me to say this, insecure about my height,

My mom is 5'1 while my dad is around 5'5-5'6 and my little brother is 5'0, and he's 13yrs old. My youngest sister is 5'1 1/2 and only 10, she is so lucky. Genetically my dads side of the family is taller, including women and men which are tall as 5'6-5'9 while my moms side of the family are average which go up to 5'3-5'8. I am latina, which I hope doesn't affect anything to do with height. I am cuban and guatemalan.

I do eat healthy, with an occasional consumption of a small bag of chips and ice cream. I do have a high metabolism. And I have been exercising with my mom since last month. People at my school say I gotten taller -- Anyway, my moms parents, my grandpa is 5'6 and my grandma is 5'4. My dads parents, his dad is around 5'7 and his mom is 5'8.

When I went to my doc. appointment around August, she predictably said I will grow another inch or half. They wanted me to exercise and that's what I have been doing. And I know stretching is a big thing, yes I have been doing that. I know that my siblings are going to be taller than me by chance, I just hope to grow to 5'4 at the max.
