TMI what is this l?

Sierra

Every time my husband and I have sex I bleed really bad. This has been going on for months and just getting worse.. I’m always in pain and irregularly bleeding. Soon I’m having an exploratory surgery to see what’s going on they think it’s endometriosis. Just a few days ago I had heavy bleeding and passed what looks like tissue im not sure? Has anyone experienced something like this or know what it is. It continued to come out in small pieces.
