I'm so sorry about your frustrations, infertility is so emotionally distressing.
The reason why I would be happy with 2 pounds in a week is that I'm lucky to loose 2 pounds in a month. I'm a very slow looser so I have had to look for other methods of motivation. That is all. I also work out nearly every day and I try to make it hard and worth every movement to maximize my time. Even with your hubby gone I might would suggest to keep taking the clomid, it often doesn't work the first few cycles so still taking it may help you get to a point where you will ovulate. Talk to your doctor about it.
