When I had an annovulatory cycle, I bled around O time, which is unusual for me, and then I bled again when my cervix began opening for AF, around CD24 in a 27 day cycle (I really thought it was implantation). I also had a longer than usual period even though it was on time. Oddly I didn't get any cramps or the usual pains that I normally get with AF during it but I bled for 11 days.
