Need some help ladies!...UPDATE

I thought I posted earlier but I can't find my post so I guess it didn't go through...I have irregular periods so idk when I ovulated but hubby and I had sex around the time glow says I ovulated. Af was due today but hasn't showed. I'm having lots of cm. White creamy thick discharge, on tp it has a yellowish tint and kinda stretchy ...is it just a sign of af coming or should I test?

UPDATE:

So still no sign of AF..still having the discharge, lower back ache, nausea after eating..tested this morning with a clear blue digital and it was negative. Getting a little concerned since I've never went this long between periods even though I'm irregular. So I text my gnyos wife (she's a nurse and works in his office). I explained everything to her and she said she thinks I could either be pregnant or ovulating. She said the cm I described to her sounds like estrogenic mucous which you get during pregnancy but it also gets like that when ovulating...ugh sooo frustrating!! My body is driving me bonkers!
