What could this be? Cd 14 usually ovulate cd28 but had a messed up cycle last month

What could this be??

I don't usually ovulate till cd28 and I'm cd13, also had alot of ewcm the past 3 days, has sex yesterday and day before so it couldn't be from that. Before this period I had most recently I hadn't had one since 16th December. So I maybe could be ovulating earlier but I wouldn't of thought this early tbh.

Any help???
