After using digital opk last few days and receiving only flashing smileys , i’m thinking I o’d the 28th?? Past 4 days EWCM cramping so I thought I’m ovulating soon. I ran out of opk test strips , yesterday using my last one showing negative. Usually 30 day cycles and last month o’d CD17. Did I miss it ? Or is it coming ??? So confused
