Cancer after complete hysterectomy

Just need some advice as I feel I am hitting my head against a brick wall at gp.   Got hysterectomy n ovaries removed in 2014....endometriosis non cancerous tumours n thickening of tubes.  And I am currently on hrt . For abt last year and half  iv been getting what can only be decribed as period pains/pain on right side going into hip area/ r leg pain/ back pain.   Doctors keep giving me pain killers.   I have eventually been referred to gyn n been waiting 6mths for laparoscopy but due to covid I know I could wait longer.  A fortnight ago i had a bright red bleed and the worst back pain ever and went to gp who are trying to help get this pushed forward.  My mum passed away with mantel cell cancer just over 2yrs ago n my aunt lung n breast cancer 2yrs ago.  So this has me worrying.   Any advise would be helpful.....sorry if this isnt related to this group
