I'm 28 yrs old with 4 living children and I've had one miscarriage. I've recently had a cycle that was a little lighter than normal. I've had cycles that were extremely heavy and passing a lot of clotted materials. I've been having some moderate pelvic pain with the passing of clear slimy discharge a few weeks before my cycle came down. Also I have my tubes tied with the last baby. Can you give me some insight on what my be going on?
