TTC and CM questions HELP!!!!

Aliyah

So I’ve never tracked my cm (cervical mucus) before but I’ve been ttc this will be my 5th cycle! I am on cd12 and on cd10 and 11 I had really watery cm almost like I was just wet! Not sticky or anything! Then today it completely changed to being tacky and and off white color! Idk when I ovulate but I have a regular 26 day cycle it’s very consistent! Is this cm I got the thick tacky off white mucus mean I’m ovulation or is this my right before ovulation cm???????
