Where's the beef?

Okay, this weight thing is finally starting to annoy me. I know most pregnant women gain weight at different times and in different ways.

I haven't gained an ounce in almost three weeks. Not an ounce! So, all in all, I have gained about 7 pounds total, and I am almost in week 18. My doctor says its fine, but I am getting concerned. I have not been able to exercise at all, and I have pretty much eaten everything I have wanted to. So, I don't get it. Normally, I wouldn't care. In fact, I should be rejoicing. But, the problem is that I am supposed to gain 4o-45 pounds. And knowing Prater's Law, I am going to gain 30 pounds in a week or something. I am just wanting this to be a gradual pound here and there, ya know?
