Am I really that fat?!?

I know that it takes me a while to get back to looking not pregnant after I have a baby. I'm not one of those lucky women who can fit into their clothes a week after they have a baby. It took me about 10 months with Kate, and so far it has taken me longer than 5 months with Tommy. But let me tell you that it really is not fun being asked if you are pregnant again! I mean come on! Tommy is only 5 months old!!!!!!! I have to vent about this because I have been asked 2 times in the last 2 weeks if I am pregnant again! It did come from 2 girls who are under the age of 18, but it still kinda puts a damper on your day. I was willing to let one slide, but being asked the second time has made me furious! I'm sure these 2 girls have no idea that they even said anything wrong, but now I can't seem to get it out of my mind! If they only knew that I have been running/jogging since Tommy was 6 weeks old, and for a month I even tried eating no sweets and I try not to eat after 8:30pm because that is when I always eat really bad. The sad thing is that I haven't lost more than 7 pounds since Tommy was 2 weeks old! My theory is that since I'm nursing my body is hanging onto everything it can because it wants to make sure that I have enough to feed Tommy. I only say this because it wasn't until Kate was only nursing morning and night that I lost my weight. So, just to clear things up...I'm not pregnant!!!
