Squats and Stiff legged deadlifts for the legs. Conventional deadlift for the back also helps the legs grow too. Don't expect miraculous growth in 2 months though - but you can make some progress.
There are also lunges, leg curls, leg extensions, leg press if you have machines.

Eat more protien too. Most women fall way short in this category. How much? That is individual. Try 40% of your overall calories as protein. You have to eat lots to gain muscle. But it is tough to balance that against gaining fat.
Do squats using weights as heavy as you can ... so that you are seriously taxed on by the fifth or sixth repetition. Be exhausted enough that you might be able to do one more rep. Do three hard sets of these (after warming up, using lighter weights). Repeat every 4-7 days. As noted, steadily increase the weights as your muscles grow to accomodate the load.
