AF late, what’s this?

Sooo Af was due today, I’ve taken a couple of tests earlier this week and nothing. Today I went pee and wiped and got this CM. Very clear and sticky. Then there was this big glob in the toilet. Any thoughts? Could I be pregnant? No normal signs of af making her appearance. The past couple of weeks I have had backaches, slight cramping but just for a few days. But not normal cramps like I experience during my period. I’ve had some indigestion. Super emotional like holy crap! When should I take a test? Is this cm a sign I could be pregnant?
