Hi Missy, once again, i'm so sorry for your loss....As for when to start, i'd say wait until at least you've got AF again, and then whenever you are ready....it's really up to you. Once you've had AF you kind of know that everything is gone and things are back to normal (hormone wise), so it's then a matter of when it feels right for you. HOWEVER, wait and see what your OB says and make your decision from there...We're thinking of you hun, and you don't have to leave us if you don't want to. We'd love for you to stay, TTC or not...xxxxxxx
