Hi, I think it is great you want to lose that last ten pounds the healthy way. I think WW online still has a special for three months. You pay for three months, and it is much less expensive than paying per month. If you have a smart phone you will love it. The entire website is one huge "community". You probably will be able to hook up with some new moms. Also activity is stressed on WW and there are probably all sorts of articles on flattening your tummy.
Don't worry about weighing yourself. Have a pair of skinny jeans you want to fit into. When they look great, your job will be done.
