Not sure when to test

When should I test

My period was predicted as the 14th I think. Which is tomorrow.. I ovulated sept.29th.

But I have been having tons of ewcm since 7dpo and when I log ewcm it keeps pushing my period later and later. I'm 12.5m postpartum and my periods have been 38 days, last month it was 32 days, I'm already on CD35, still having tons of ewcm, had cramping and thought period was gonna start but it's just ewcm still...

When do I test? I keep thinking I'll wait until my period passes but idk when that is gonna happen 😂
