Your doctor will be able to give you the best answer to this question, since a lot depends on your health and the circumstances of your loss. However, your physical readiness is only one aspect. Consider if you are emotionally ready, or if your partner is willing to try again too. It is also crucial that you have grieved your loss, and that your desire to try again is not an attempt to forget or run away from your pain. You owe it to yourself to heal, both physically and emotionally, and take care of yourself first.
