TMI CM PIC!

Tia
I have irregular periods so idk when I ovulated, but I did have sex around the time glow says I did. Glow says I'm supposed to start af today but she hasn't showed. I'm having this cm when I wipe. I'm usually dry right before af. I'm feeling the slightest bit crampy...should I test or just wait it out and see if af shows since I'm so irregular?
