Hysteroscopy and biopsy waiting time?

Hi all 

I haven't been diagnosed with cancer but after seeing a gynaecologist this week he said he would refer me urgently for a hysterscopy and endiometrial biopsy. I called today to see when that appointment would be and was told I have to wait until 20th October that's practically 11 weeks away he is putting me under general anaesthetic as I have had previously endiometrial ablation some 12 year ago. 

Can anyone tell me if this is normal or acceptable? Much appreciated.
