I am petite as well and opted for the couch potato approach. Looking back at my sway my only slight regret is not doing the exercise. But I really doubt I could have kept up with the diet and exercise without loosing ovulation. We are expecting boy #4. I know this baby boy was meant to join our family, so I am pretty sure exercise or not he would be ours!
Do what works best for you, but ask yourself now if you will regret not including it in your sway if you end up with a boy.
