hello! - i have had this problem as well - i was put on a tablet called norethisterone - i have just had to come off of it as i was on it since january - when i had my last bout of bleeding - i started bleeding again last Thursday - and i just hope to god i dont start bleeding bad again... i s'pose this is more reason to lose weight ! as being over weight dont help.
I know what you went through and i wouldnt wish it on anyone... my heavy bleeding is connected to PCOS - so might be worth getting checked out for that?
Best wishes hun -
