13 days late - Any input will be greatly appreciated

Hey ladies!

So I am soon to be 14 days late according to this app. My last period was August 4-8, the app says I ovulated August 22nd. I did tests at day of missed period, 5 days late, 8 days late and lastly 10 days late... they were all negatives.. my period is still not here, I don’t feel myself at all. Brain foggish, intense cramps 4 days ago, bad pelvic pain 6 days ago. Nauseated, constipated, tired, increased urination and highly irritable.. today I had super creamy/sticky pale yellow discharge.

This was taken last Thursday (4 days ago)
