please help =0)

hello - so i have been lifting heavy for about 2 months now - i started off with new rules for women, then when that got to complicated i switched over to strong lifts 5x5 which i am really enjoying at the moment. I tend to lift about 4 times per week, then on the days off i am going into the gym and doing some cardio.
i just wanted to check that i had selected the correct activity level -
so i'm 5'2, i weigh 11.2, i''m 30. i work as a pharmacy tech so i am literally on my feet all day walking backwards and forwards in the dispensary, lifting heavy things ect - i work 40 hours per week - i'm following a lifting programme and train 3 times per week, i some times try and fit in a session on saturday as well, but this isn't every saturday, on the other 2 days i do some cardio in the gym each session tends to be about 40 mins.
So i choose the 3-5hours per week, moderate exercise option do you think this is correct - i would say i do more than lightly active but not as much as the strenuous exercise.
hope this all makes sense
