First AF after MC?

Lena • happily married Yogi, Blogger,
I'm wondering when my first AF after MC should start. I miscarried (week 9 but stopped growing week 6) at the end of April and still nothing. I have some light cramping inbetween but no spotting at all. I honestly hate this waiting game as its so unpredictable right now. How long took it for you to start?
