When should I test?

When should I test? I had clear stretchy CM on the 9th and 10th. 
It went to creamy white CM  the 11th, and then 2 days ago, i had CM that was creamy and white but it also was like I went pee slightly at same time. ( I have NEVER had that happen before) usually it's just white and creamy or clear and stretchy. Just watching for more signs now!
