Weight Gain?

Lindsey
Sorry if this a taboo or personal question... but I'm wondering if my weight gain is normal/comparable to others.  I've gained about 10-11 pounds so far, and I'm 20 weeks along.  I'm just concerened because I feel like I'm famished all the time and am eating quite a lot, so I want to be sure it's going to the baby and not to other parts of my body, haha!  I know we shouldn't be too focused on weight gain because it is a part of the experience, and it's okay, but I just want to make sure im staying within a healthy limit.  Any thoughts would be great!  Thanks so much :)
