Weird period ?

Brenda

I have my tubes tied, 5.5 years now. So I was supposed to start on the 14th. Instead I started spotting very light pink sometimes brown on the 15th. Stopped and then started spotting again on the 17th thru the 22nd. 23rd it was bright red. But not heavy. I put a tampon in. I was cramping pretty bad so took the tampon out and this blob of something came out. It's kinda flesh colored with blood lines running thru it. Blood on one end. Maybe a weird blood clot? I finally stopped bleeding last night. So 11 days of total bleeding. I went to the hospital, just took blood work said it came back fine. Diagnosis, heavy period, even tho I wasn’t bleeding heavy. Didn’t ask about what I passed either. I took pics. Any ideas?
