Spotting started this cycle in day 17. Lasted for about 5-7 days. Then full blown AF - very heavy for 7 days now. Came off the pill in November. Didn't expect regulation to take this long. Wondering if something more is going on. Did anyone have trouble with ovulation (no positive opk since stopping), irregularity (42 day, 99, 17 day cycle) and flow when they stopped BC?
