Am I too short?

I'm 5ft5 and 16 years old but now that I'm in college I feel like 5ft5 is rather short. I want to grow at least 2 inches taller to 5ft7 and the maximum height I would like is 5ft9. I don't want to be a model or anything I just want my body to reach its full potential if you know what I mean. I have been adding stretches to my exercise routine and have carried out the cobra and superwoman exercise for 2 weeks now. I feel like my abs have become more stretched out or maybe I have just lost weight but my height has remained 5ft5. Has anyone else tried to become taller and succeeded? I have heard that at a certain age the growth plates stop and so you can't grow taller after that. I'm wondering if that may be the case? Genetically I don't think there would be a problem with me being taller because everyone in my family is tall excluding my mom. Any help/advice?
