What type of dip is this?

Cervix is high. But it’s closed tightly. Still having creamy cm. Instead of ewcm. If its pre ovulation dip does that mean ovulation will be occuring today or already happened? Or maybe my ovulation dates are off, tests last week were a lot darker than this week just not as dark as the control line so I considered it negative. So would that make it implantation? I’m so confused
