I just had a miscarriage... I feel so low. How long do I wait until I can try to get pregnant again? Gynae said I should try right away, but I feel too depressed right now

Release all hurt, pain and disappointment to the universe. Once you clear your story and close that chapter, then you can move on and create your new stories.
