well, you will be able to go en pointe, yes, but nobody knows how long it will take! you need to have the adequate strength in your feet, ankles, knees back and stomach so that u don't hurt yourself.in theory, as u have finished (or almost finished) growing, it should take you less time than normal to get onto pointe, but everyone is different. i started ballet at the age of fifteen . and it was a year and a half before i started pointe work. whatever u do, don't go up on pointe until you teacher recommends it, otherwise you could seriously damage your body for life
