I am on Birth Control and I am worried cause my Period has been going for 13 days now! is everything ok??

I have been on Birth Control for 7 years, I also have Endometriosis, i have had 4 Laparoscopy's to have it removed.

I am on Birth control and My period has been going on for 13 days with really large Blood Clots. My doctors office is closed until Thursday and I am Worried. Is this something to get worried about? Is it related to my Endo??

anytime your period last more than 7 days something is wrong, if you are having heavy bleeding with blood clots don't want to alarm you but this needs to be checked out asap even if it means the ER, would discontinue b/c and sex until this is sorted out your body is telling you something is wrong!
