Faint OPK positive

Sana

So I decided to do an ovulation test today even though glow said my ovulation day is 3 feb. It came back faintly positive. I have medium to heavy creamy/watery CM. After entering in glow it says my peak day is tomorrow! There was no option for noting faint opk. So I think I’m still a few days away. It’s my first time testing OPK. Help me understand this.
