It is possible - anything is possible!

I find I get a lot of EWCM during AF, I don't know how normal that is, but I'm wondering whether it is maybe some of that lingering? Looks like you only need one more high temperature to confirm ovulation, so it could just be a matter of wait and see.

I'd also not assume that it was definitely ovulation then - it is unusually early, so I'd continue to keep your bases covered and continue BDing and charting carefully until you are absolutely sure you have ovulated.

Good luck!
