I had a D&C too for MMC, as bleeding would not stop, so wasn't really anything left to pass /bleed after, just light spotting like the start of a period amount. But this did mean I had only 26 days to wait till my first period started. (I normally have 28 day cycles and I think if I hadn't have been lucky enougth to fall pregnant straightaway again this next cycle I would have had a week longer one than normal, as I ovulated late they told me as I was 6 days behind in dating by the 12 week scan to my LMP dates, this I agree with as saw signs of ovulation EWCM after we had stopped bedding and so went again, and this I think is the only way I caught the egg for my son. (Waffling now, but just mentioning this to say I would bed more / more regular and for longer after a MC as it really can change when you ovulate and length of cycle if TTC straightaway)
You really are more fertile after - so wishing you lots of luck X
