I'm a 56 year old woman and since I was around 48 my periods have been very hit and miss, sometimes going months without a proper period but always having a brownish discharge most days.  I went to my dr in July and I was refured for an internal scan with what I was told a biopsy which was done by the specialist. Today I had a letter saying my histology results were normal and there was no need for concern. I had a slight thickening of the womb and they said they were arranging for me to undergo a minor investigation before being discharged back to my dr. What would this investigation be? I'm still bleeding everyday so how can that be normal? Very confused
