Last night I had the most agonising pain. It seemed to start around my cervix and spread across my pelvic floor. It was so intense I could not even speak and lasted for about 80 minutes. I would describe the intensity as on par with childbirth and I could not move. After it subsided I felt sore, bruised and had a distended stomach. Today I have started bleeding - bright red thin fresh blood - I have the mirena coil and do not usually have any bleeding ( although 6 mths ago I was having some odd spotting) I have been diagnosed with endo for 20yra and adeno for 8 mths. Anyone have any ideas as to what happened last night - I don't want a repeat of it I know that!!
