Hello, I saw a Consultant at my local hospital last Monday 24th January for post menopausal bleeding I'm 54 years old. Had a letter this afternoon telling me my endometrium is 9mm and they will write in due course with biopsy results. I had a Mirena insertion whilst I was there and since I had it put in I haven't stopped bleeding. The person who did the Hysteroscopy said she couldn't see anything alarming but I am concerned about the 9mm thickening. Do you think I should be concerned ?
