How soon did you successfully try to conceive after miscarriage and D&E?

Lilly
Currently in a hospital bed after my d&e, waiting for the cramps to settle so I can be discharged. Had a missed miscarriage, baby stopped growing at 6.5 weeks, my pregnancy symptoms went away and I found out at ultrasound at 3 weeks later. 
I'm so upset, but want to try to focus on the future. Would love to hear your experience on when you conceived after a miscarriage - my doctor says to wait 2 cycles (2 periods not including bleeding after d&e). Whatever it takes to get my body strong again, but I also don't want to "waste time".. 
Lots of love from a broken-hearted ❤️
