My sexual life is screwed - where do I complain?

Hi, FTM here. In start of August I gave a birth at Princess Royal Maternity and had a 2nd degree tier. I also have vaginal septum, so had to be taken to the theatre to be stitched up, as I lost a lot of blood. Now 3 months later it still is very painful to have any sort of intercourse. I went to see GP, to be told that the line to see gynaecologist is around 16 months. Is there anything else I can do, like to complain to hospital for essentially screwing my sexual life? What are my options besides going private?
