This is my second baby, and started out heavier than with my first as well. I was doing really good by 23ish weeks I only gained 3 lbs. But I've gained 15 more since and I'm 34 weeks today. I blame it on my lack of energy and inability to walk around much. I was a lot more active earlier on, but with the anemia and the pubic bone pain starting, I haven't really been out as much. BUT that just means I'm gonna have a harder time losing it all after she's born.
