Okay so af was late and finally showed up today.. Was fine all day regular bleeding and now I have tissue and blood clots that are ridiculously big -.- and they just fall out, I can feel them.! I'm in horrible pain now and was when they were falling out.. This happened during my miscarriage back in January and has happened twice before that but no known miscarriage.!!  Can anyone help me as to what this is.!! I have had a test to take out endometriosis , and it wasn't bad .. So idk what's wrong
