So... I've only just begun charting... I started mid way through a cycle... Yesterday, I went to the toilet, and there was a fair bit of blood on my undies. (Sorry TMI). I wiped and there was a bit of blood and the tiniest clot... And nothing since... I had a 19 day cycle!!!! My average is 34, with most of my cycles being between 29 and 36 days... Anyone have any ideas?
