I too started 10days early on my last cycle i started on cd31 instead of cd45!!
I was so shocked cause since xmas i have been counted my cycles like bad and they have been 45, 45, 41 etc
i am now confused to when i will ovulate!
I've posted an update. I still have the bleeding, however now it's constant and not painful, but bright red, and very small clots. It's been 8 days since bleeding/spotting started.
