I don't know your history, but a lot of different things can contribute to a light period, but it can also just be the natural cycle of things. I wouldn't worry too much unless it becomes consistent (i'm sure you've ruled out pregnancy as a cause). however, i have bled a little from ovulation before, and at 10 days, it would make sense for you to be O'ing now, ecpecially with EWCM. It could also have been caused by rough BDing or something like that.
Some women do have spotting during O.
Thanks for your comments!
I have never bleed during o before. But that is good to know that it could be because of that.
