Confused! CM eggwhite-like post O. (TMI)

Lucy

Somewhat confused. AVA, Ovia and Glow had my ovulation day (plus or minus 2-3 days within each other) on the 3rd week of June. Egg white mucus within that few days. It’s about that time for AF to come-had cramping yesterday and the day before and I thought it would come, so I placed my diva cup in. Both yesterday and today, this results in being in the cup. Please someone enlighten me. Has anyone else had this happen with their CM post ovulation? TIA! (Negative preg test yesterday and the day before).
