Welcome, welcome. It sounds like you have been through a lot. DH and I want to have another baby but a) I wanted to lose much more weight first adn b) Im afraid that once i lose weight, i won't want to get PG and gain it back. So kudos to you for making goals and (so far) achieving them!
Start small and keep on trucking. Hopefully you will find inspiration on the board and other outer resources to help you achieve success. The weather is gorgeous outside, so go do something!!!
