please someone help me!!

Okay, AF was suppose to come 2/12. I've tested a ton of times, all BFNs. The weird thing is today I was having ewcm. And quite a bit of it.

I took a ovulation test. And it was the darkest I've ever tested. But still a negative. I don't know what to think. Could I be ovulating this late? Anyone gone through this, and what was the outcome of it? Thank you.
