Cardio exercise

I've doing some cardio exercises every week lately as I really want to lose weight and shed extra fats on my belly. I'm kind of conscious how my belly looks since I gave birth. I hope I would lose weight in two months. I really have to be dedicated to attain this goal. I think this can be very challenging. I noticed that I can easily lose weight if I jog, so I'm going to do that often. I have a gym membership, but I haven't started going to the gym yet. :-( I want to go to the gym very soon so I can do more cardio exercises, like swimming, treadmill, etc.
