Open Question: After you get your period...?

I'm born premature buy 4 months. As in, my birthday is suppose to be sometime in December but instead its August 4th. Yes, I'm a miracle baaby! :) Back to my point.. 1. I got my period in grade 4 the day of Valentines Day and I am now almost 12 and at the end of grade 6. Since then I've grown about 6 inches. Now, I am 5'2 ½ or maybe 5'3 but I'd like to know if its possible that I reach about 5'7 or 5'8. My mom is 5'8 and my dad is 6'7. What do you think? 2. About a year ago, I weighed 80 pounds and had the body shape of a banana and now I have the body shape of a pear and weigh 106. I was a size AA and now I'm a size A34. Is all this normal? Thanks for all your answers! :)
