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 January 2019, I felt dead for a while I was so depressed. I took time to grief and come to understanding with what happened, here I am 6 weeks and 5 days pregnant with what might be twins. keep your head up. ❤
