First Aunt Flo after Miscarriage

Alice

I had a miscarriage in August. I bled for about 3 weeks and think maybe it turned in to AF. On one of my lighter days bleeding I noticed water like CM and decided to test ovulation popped up at peak time. Hubs and I didnt BD due to bleeding still but I stopped about 3 days later. According to app AF should have arrived on 9/5 still nothing no cramps nothing. When did you get first AF after miscarriage?
