Blood clot- 5 days PP

Is this reason for concern? I’m already 5 days PP so I didn’t think I would still have any clots. My blood is still bright red but I don’t soak a pad every one hour, it’s actually pretty light bleeding and then no other signs of concern other than this huge clot. It’s the weekend so I can’t call my doctors office but I really don’t want to go to the ER especially if it’s not necessary. They did say to call if bigger than a golf ball but idk what size this is?? It’s bigger than a quarter and I felt it come out when I was sitting down so I went to the bathroom and it was in my pad.
