I have never had any problems with periods being heavy its always been the opposite another reason why it took so long to be referred to a gyno. I have endo had a lap op down on the 1st still in lots of pain and still lying in or on my bed as i cant move about much at all. I woke up the other morning with period cramps the usual painful twisting and though oh god here goes. 7 days early as well but i went to the loo as you do and yes it was the start of my period but then it stop almost as soon as it came and the period cramps were gone next evening. Has anyone else had this?? I wasnt sure if maybe it wasnt my period coming and was something from after the op.
