I know what you mean! I have done it too. I was told to only walk as anything more was too masculine & strenuous, so I gave away running & combat classes and like blonde assassin have gained approx 7kgs. I am back to gym classes and running again and feel it has given me a new lease on life. My approach is to live life and not let TTC consume me. Much easier said than done! I agree that I have made changes to be financially, emotionally & physically ready and never imagined my body would hold me back.
