Any ideas what caused the growth spurt? I've known adults that had it happen from taking (prescribed) hormones or being pregnant, but have no idea about your situation. Something may have made the pituitary get busy.
oh yeah I went through a growth spurt with each kiddo I had... my feet and boobs got the worst of it... I went from a pretty size 7 to a huge big foot 9.5... and I went from a decent c cup to spilling out of a DD (I refuse to buy those huge holsters that cover your whole chest like a bullet proof vest!) and no one make a pretty size F I think it is... hahaha my hips spread as well... but I had no booty before kiddos so that wasn't so bad to finally have a butt! hahaha
crazy how even after the teen years your body never does stop changing!
