EWCM but negative/low OPK test? Asking for a friend!

Becky 🌈 Foley

I’m still new to this charting and all.. So I have been regularly checking my temps before getting out of bed and taking OPKs with FMU and when I get further into my fertile days I test twice. My OPKs have still been fairly faint but I just wiped after going to the bathroom and had a medium amount of EWCM. My calendar says I’m 4 days away from ovulation. Do I believe my calendar and the OPKs? Or does my cervical mucus tell me I’m going to ovulate sooner than later? Can you have multiple days with EWCM?
