Ewcm?

This may be a stupid question but how do you tell the difference between ewcm and sperm? I have been having ewcm since Thursday. I never have it this long. I’m wondering what day of ewcm I should’ve ovulated? I quit doing opk’s bc it was just too stressful. I know my body and normally can go off of ewcm. I’ve just never had this much so I’m wondering if some of it could be sperm. Yesterday afternoon, I seemed to get a little drier and now I have a lot of ewcm again.
