Please answer, braces question..?

I have an orthodontist appointment on the 29th, and it's a consultation to look at molds & treatment payment options. This is not my first appointment at the ortho. I've already had xrays and molds done. (last week) They have also shown my parents how much the braces will cost. So what i would like to know is how much longer will it be until i get braces? (i also don't need any teeth pulled) Please answer...Thank you!
