Flashing smileys for 5 days - confused

Hey guys! I’m so confused. I’m on CD16, and I’ve had “high” fertility on clear blue digital ovulation readers for 5 days now and haven’t reached my peak yet. This has never happened to me before, I usually get two days of flashing smileys and then peak. I also feel like my cervical mucous is non existent which is also not normal for me. Maybe my ovulation is late? 😩 Has this happened to anyone before and you successfully ovulated that month? Thank you for your input!!
