OPK getting darker?

St

Used clearblue digital ovulation after my period ended this cycle and got my peak CD13. I was also using the easy@home strips and never got a positive with those. But did have watery cm around CD13 so assumed I was ovulating. My cervix has remained high and it feels open !? My boobs haven’t been hurting, which made me quite hopeful as I always get sore boobs after ovulation and this time, nothing! Did an easy@home OPK today and it’s darker than it’s been the whole cycle!!?? But I’m CD20 today. It’s too late to ovulate right? Would clearblue have been incorrect? I’m so confused….
