My AF is not due until 9/29

My peak of ovulation was either the 13th, 14th or the 15th.

My cervix have lowered so for me that's a sign my ovulation has stopped.

Today I woke up and noticed my nipples are very sensitive to the touch and are throbbing.

My cat walked on my stomach earlier as well and it feels extremely sore too like mild cramps and also gassy.

I have this headache that won't go away and I've felt dizzy/shakey and extremely tired.

What could this mean? I never feel like this through ovulation or before my period so I'm confused.

If I was pregnant by chance none of this would be happining right now right?

I'm just confused and wondering if anyone could shed some light on what may be going on.
