IM REALLY SCARED PLEASE HELP

Sydney
So I just got off the pill on October 21 and that was the last day of my period today and I'm still kind of bleeding. Like it's end of period kind of blood but I finished my period on the 21st. Today I feel really sick as well. I feel bloated and sick to my stomach is this from the pill? Also I had protected sex a week before I stoped so I was still on the pill. I just want to know what's going on. I'm scared so can someone please help me ?!?!?
