Period with provera

Okay so I had taken taking provera for 10 days (started on the 8th and finished on the 17th) and I got my period on the 24th which was a week later

When it first came on it wasn’t too much blood but I figured it’d just get heavier because it’s just started.BUT for some reason it’s still a super light period like not even enough to fill a pad YET I’m having every symptom so badly

Period poop

Terrible cramps

Fatigue

Hungry

No energy whatsoever

& Back pain

Is this normal ?? Like it’s barely even there when I wipe it doesn’t even show in the toilet bowl when I pee!!

I thought it might’ve even been implantation bleeding but I had taken a pregnancy test today it came back negative
