Hi, I have endo (have for approx 20 yrs). My periods have always been regular + or - 1 day until approx 9 months ago. Since then it's been all over the show ranging from 9 days late to 7 days early & twice my period had started full flow one day, stopped dead later that evening only to start again the next day. I thought maybe at 39 it was the perimenopause. I have other symptoms including pain & being unable to insert tampons after 1st day of period anymore. Was referred to endo specialist who thinks I have Adenomyosis based on an extremely painful internal exam. I can't seem to find any reference to periods starting and stopping as being a symptom of Adenomyosis so wondered if anyone else had experienced this? Have decided am definitely coming back as a man if there's next time!
