you 'think' you are bleeding again? Surely you will know if you are or not?
I had a scan for gallstones, but be careful, the scan only shows stones - you need a Hida scan to show if your gallbladder is functioning properly (if they suspect that is the problem). I haven't had the agonising pain that people with gallstones suffer, but have had pain and symptoms, hence them checking the way it is functioning.
I don't think bleeding is a symptom of gallstones though. If you are bleeding for no reason though, that alone needs to be checked out Fab.
