When is it okay to try again?

Mrs. • Wifey. Mommy to 2 precious baby boys 💕
I just recently suffered a missed miscarriage and had it induced with misoprostol on 4/20/16. I know that I am barely out of the recuperating and healing stage. But I feel that the only thing that's keeping me going is the hope and possibility of soon carrying a baby to full term. 
My doctor said to wait 2 cycles, while I've heard others try after 1 or even immediately after their miscarriage. Is there any doctors on here hat could explain why the difference in waiting? Any of you ladies waited too little or too long and had a second miscarriage? Any of you tried right away and had a healthy rainbow baby? 
Please shed some light for me and my thoughts are all day all consuming.
