Weight gain during pregnancy

Jessica
I'm in the fifth month of my pregnancy and I've only gained two pounds. Is this normal? I feel like I'm eating and snacking constantly. I am trying to keep my snacks healthy...cheese, cucumbers, carrots, apples, peanut butter...I do still eat an occasional piece of pie and fast food. I just want to make sure I'm gaining enough weight for the baby. My doctors haven't said anything so I'm not super concerned..just curious what's normal and what isn't. I weighed 110 prior to being pregnant and now I weigh 112. Thoughts, opinions??
