Confused?! CM has changed loads?

Been TTC for 15months. I stopped spot symptoming for last 6 months.. but i know my body quite well at this rate...

Every month week before im due on i normally get the creamy cm like milky lotion before AF arrives. I normally get really bad cramps 3 days before period.

Anyways last night i couldnt help but think i had like little stabbing pains in my right side. I ovulated from my left so i know it couldnt be implantation until i read a storey a women ovulated on the left and implanted in the right side.

But my CM past 3 days have been CLEAR white very stretchy? Does anyone know why?
