When do girls stop growing i am 17 & 183.7cm tall. i still get growing pains and have grown in the last few months? can i stop myself getting taller?

Genetics: Nope. You cannot stop yourself from growing if your genes have programmed you this way. You are getting close to the age when you will probably stop growing, but this is a bit off for now. Perhaps your height will lead to some great opportunities. Studies have repeatedly shown that taller women make more money in general than their shorter counterparts.
