so i had unprotected sex on september 12th. i had weird pregnancy like symptoms before my expected period date. i took a test & it came out negative. i had bled on the days of my expected period so i guess you can say i had a period*. but even after i stopped bleeding i feel bloated 24/7 , my appetite is going up, and i’ve started growing hair on my tummy. what could this mean ?

* the bleeding i had on my period was like period blood. red . heavy/ sorta heavy . blood clots .
