Pcos, opks, and ovulation!

Has any other ladies with pcos ever dealt with taking opks and they always end up being negative? I've been testing since my af ended on the 6th, I had ewcm the day before yesterday and yesterday. Yesterday was heavy and today I don't have it anymore but I've been testing and still no positive surge. So does that mean I ovulated or not and bc I have pcos it doesn't pick it up? So aggravated.
