How soon should i begin to see results if i keep this up?

i'm 5'4" and about 130 lbs... i want to work on losing fat & getting more toned. i started working out last week. i have been doing 30-35 minutes on an elliptical machine which comes out to be about 3 miles. also, my apartment complex offers cles so i have been going to the cardio kickboxing and either the boot camp or the body sculpt cl. i am cutting out junk food and drinking more water. just wanted to see if anyone could tell me about how long until i should start seeing some kind of result. i've tried stuff before but never stuck with it. i really want to this time. thanks in advance!
