Had a blighted ovum very early suggestions on how long I should wait to start TTC again?

I had a blighted ovum at only 3 weeks which most people dont even know they are pregnant it was actually a fluke thing I even found out. I only tested because I hadnt had a period in over 2 months which means I got pregnant some where in there without having a period which I was shocked about because I didnt realize that could happen. How long would you suggest I wait before I start trying again? I have had a pelvic exam and all is back to normal I did not need a D&C as I wasnt far along. Just asking for a little input thanks everyone
