My doctor advised to wait until I've had one good period so that my body has had time to heal and then we can start trying, if we are mentally and emotionally ready. I'm thinking we'll start TTC as soon as that happens unless getting my period sets me and/or Billy back emotional-wise.
I think everyone is different. My sil lost her baby almost 4 years ago and still has not ttc another. Each situation is so different. I think only you will know when you are ready. I think it is important to wait until you are emotionally and physically ready... I guess as much as you can be.
