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 an ectopic pregnancy 2 years ago and pg now my last period was on the 7th and only blead for 2 days and then nothing now I'm bleading light went to doctor and they said its ti early to tell I'm just really confused and lost
