13 DPO, positive OPK?

What could be the cause of this? I ovulated the 12th of January confirmed by OPK and BBT. I also got EWCM on Saturday (19th) through Monday (21st). Then I stopped getting any CM until today and it was creamy.

Here is my OPK from tonight:

** Yes I know the instructions of an OPK and that it’ll be positive for Ovulation, Pregnancy or before a period. **
