Question a little tmi!!

Has anyone ever had a "provera period" that only lasted 3 days the first 2 days were very very heavy and yesterday it was hardly any and today its just the top of the tampon when I take it out and its very very little. I keep one in just in case though bc I heard periods from provera are normally very heavy for atleast 5-7 days. So today idk if I say im still on my period or is it whats left over I guess I can say.
