Blood clot after birth *TMI PIC*

Hey guys this is TMI so if you feel uncomfortable, don't look! Just went to the bathroom, I'm 6 days PP and felt this slide out. I know they said if it's smaller than a golf ball it's okay, it was probably the size of a quarter/half dollar? But should I be experiencing this this far out? How long should you be getting clots still. I rang my doctor already waiting for them to call back but I just wanted to put it out there and ask you ladies who have been through it since I'm a FTM. Thanks for any responses!
