Thoughts? 9 DPO symptoms

Sh

Currently 9DPO with a negative FMU test.

My symptoms started an hour or so after my test.

Bright green poop (sorry tmi but I’ve read it can be a symptom)

Dizzy and faint feeling

Fevery feeling in my body (no fever)

Eventually had what felt like a low grade fever

My lower back aches and my legs feel worn out and weak.

I’ve been hot/cold all day

My body feels like I have the flu or something but nothing else besides a very minor runny nose. Thoughts? Are these early symptoms perhaps? My body aches like I’m sick. This is our 10th cycle TTC and first time I’ve felt like this.
