HELP !!!!

This month my period was 2 days early but it wasn't like a normal period... it was really dark and only lasted 2ish days normally lasts 4-5 days

I still feel like i have pregnancy symptoms still bloated my teeth are so so sensitive, i feel hungry then i go to ear and feel sick at the smell and cant eat. I feel tired all the time and pee more frequent!

Could it be break through bleeding ? I done a test 5 days before my period was due and it was negative .... any advice ❤️🌈
