some times both and someimes just one.. and yes am a large person ..

ok thanks for your help !!

Is it just one or both? Your mother should get you established with a gynocologist to make sure it is only growing pains. It shouldn't hurt that bad, but that may depend if you are a large person.  Hopefully you have insurance and you can see a dr. This is a rule out attempt. You need to be sure you are healthy, and not wait. 

nope .. my period still far maybe  2 weeks

Are you getting your period soon--sometimes that can do it.  Or just hormones in general.
