Help!!!

Im NEVER late. Af was supposed to come today still no where to be found. I ALWAYS get period shits, bad cramps, and eat everything in sight the day before I start. I have got NONE. I'm experiencing thick and then thin milk white discharge, which I've never gotten before. Ever. Will attach photo. I don't feel like myself at all. My areolas are getting bigger slightly darker but nothing major. Should I wait a few days then test or what?!?!
