Ovulation question. Confused ..

So does that google answer mean leading up to the day of ovulation it’s clear but the actual day I will get a faded test result. LH has been slowly getting darker over the last few days. Then within 24hours it went dark then started going light again. Today I have slimy cm. What my fertility nurse always told me was good cm. (Egg white) Re tested today along having this slimy cm. Got a faint line on LH TEST I use to use clear blue digital which was a lot clearer to use.
