I have always had a long cycle for years it was between 40 and 45 days long. My husband and I have been trying to get pregnant for the last year and a half, in that time I have been doing lots of things to help my cycle including taking myo onisotal. My periods have become less heavy and my cycle has been slowly decreasing now it's somewhere between 35-40 days. This month was weird because I had spotting for 5-6 days but no real flow and it started on day 28 of my cycle. I have never in my life had a 28 day cycle. I don't know if this is just my body getting into a normal range part of me is wishing that that was implantation bleeding but I think it would have shown up as a positive by now right? I would be on day 40 if that wasn't an actual period.
