Last period started 31 days ago. My average cycle is 26 days so I'm now 5 days late. I use an app to track them and they sometimes vary by a day or two (longest ever cycle has been 28 days and that was only once), shortest 25 but usually 26.
I did have some very light bleeding on day 13 which went on for about three days but not a period and have been on and off feeling generally wierd since. Had bad cramps 4 days ago but no period then 2 days ago felt teary and thought PMT but still nothing.
