God Love ya..first because you have 4 :) Second because you have 4, and want another! I agree that if you believe you are stable in all areas as far as financially, emotionally and such and you've already done such a great job as it is, then do it! Children are amazing, sure they can be rotten sometimes, but they're yours and you love 'em for it. You mention too that your husband would be willing to try for another, as well as yourself, so really, you already know you want one, and I think if you already know you want another child, then try! You say you may not be able to get pregnant again, but both of you would accept it if you did, so there is no harm in you trying, because if you succeed, then you've got another wonderful reason to live and love life everyday, besides the 4 you already have. Also, yes, you can always get your body back, and I dont think that's selfish at all, we gotta love ourselves before we can love anyone else. I only have one child, he's 8, but I would definately like to have one or two more. Hope everything works out for you, just remember, it's just one more to love, play, laugh and grow with, and there's nothing wrong with that.
