Hey Jenna,
We have a wonderful "Getting Healthy to Get Pregnant" group you might want to check out...what a wonderful thing to motivate you!
We also have a ton of groups to check out, like the 100 lb club, for those on their way to losing or who have lost 100 lbs or more, plus groups by age range, eating plan...just a lot of places to explore. So look around, find a spot, and settle in! Can't wait to get to know you better now that you've come out of lurkdom.
