Hello Doctor. I was suffering from heavy flow in last month ( 20 + days).Then my gynac suggested me 30 days course ( Tab Regesteran and Tab Tranera ).After completing this course I had ULTRASOUND PELVIS test.(Result : Endometrial echo central and thick measures 23.4 mm ). I know this is not normal thickness.What is reason behind it and how can i cure it now ? .Is it a serious health issue?
