I wouldn't get too discouraged if you got on the scale and didn't lose any pounds that week.  When your body is losing weight it goes through ups and downs.   The important thing is sticking to the program.  I need to get with the program and lose some weight too.  I fear I've put on a few pounds but I have no way of knowing since the 9-volt battery died on our scale and I'm in no hurry to buy another battery anytime soon since they come in two to a pack instead of individuallly. 

Waiting and watching. And with you.

You will hit valleys my friend but you must continue to work the system. If you keep a good log of food and exercise you can better identify what part failed, if it does.

I see this in the gym often. I know guys who weren't getting the results they were after either and attributed to their body or this or that but weren't eating properly - just an example. Like my Dad who works out and can't gain weight because of it but he doesn't eat 5000-6000 calories a day like he needs to to really build mass.

So document, document, document and if you hit a wall you will get around it quicker.

Ed is right... and many times you really need to see just how far you've come doing what you're doing.  That way, when you do hit the occasional wall, you can look back at your logs and realize, with confidence, that you are still "doing it right."  The results will come, even if they don't come as quickly as you would like.  But if you only look at where you are and where you want to be, it is easy to get discouraged.  Its okay to look in the "rear view" mirror occasionally to see how far you've come.

The other suggestion is to break up your fitness goals into bite-sized pieces.  "I want to be able to jog (x distance)."  Then up the goal.  "I want to weigh (x pounds)."  Hit that smaller goal, celebrate, and then set the bar higher.
