TTC (confused)

So I’m 3 days late on my period, last week I was so fatigued on Thursday I was so nauseous had some mild cramping also when I got home from work I felt like a flutter for 5 secs and I also cried for 5 mins because I was so tired but couldn’t sleep.. went to bed at 2 am that night & was extremely hungry. Also I haven’t been very hungry and very picking about what I eat

On Saturday I wore a panty liner because I felt like I was going to start AF, I went to the restroom and seen this on my panty liner.. Oh, and I’ve been having lots of clear CM when I whip

I took a test today and it was a hard Neg.

Any thoughts???
