Why do I have ewcm 10dpo?

Irene

The past 2.5 days I have had lotion like cm. Like a lot of it and now I just went to the bathroom and it is EWCM. I’m suppose to be 10dpo today and af is due in 4 days but I’ve never had ewcm after ovulation before. I’m usually pretty dry after O. Does anyone know why or experienced this before???
