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

i had a miscarriage in Nov and im now 10 weeks pregnant.. i was so far along doc suggested i waited the 3 months to retry.. but i would suggest really take the time to accept what happened so u dont overthink everything as bad with the next pregnancy
