TMI blood pic before ovulation and period

Why is this happening? I haven’t ovulated yet and I’m on CD 23. Last cycle I ovulated on CD 25 which was after a miscarriage and I had a regular period for December. I’ve been bleeding like this and spotting for 6 days....started on CD 18. And a one day spotting on CD 12. I had EWCM on CD15-16 which is around when I normally ovulate...but my bbt hasn’t confirmed any ovulation yet.
