Hi, I am 15, turning 16 in June,2013. I had my period when I was about 12. But until this day, my period is still irregular. I haven't seen it in 3 months and I'm pretty sure that I'm not pregnant. And I am 5'1 and 3/4. So .25 more inch and I'm 5'2. I wonder if I have stopped growing, or can you give me any tips for increasing my height? Thank you!
