I am 16 days post miscarriage (well, 16 days since bleed it started....on Christmas morning).  I'm not sure how to time this...not exactly sure of much right now.  But, my dr said we could start trying as soon as we got a negative pregnancy test.  So, I waited until 2 days ago and took a test...or two, lol, and both were negative.  I took another yesterday morning with FMU just to be sure...and it was for sure negative!!!
