At the end of my rope...

I have been bleeding vaginally for five months. I have been to my Gp. I have NO Sti, no std, no HPV, no cervical ovarian or uterine cancer. I've had my smear, pregnancy test negative, I've had urine test blood test, I've been fobbed off with the coil which migrated, they've tried mefenemic acid, tranexamic acid, progesterone, cerelle, northisterone. I was promised a hysteroscopy a d&c and a laparoscopy they done the hysteroscopy but not the d&c and laparoscopy(as Was promised !!!) they found no fibroids or polyps either . The GP and specialist Gynae have left me bleeding until they have a multi disciplinary meeting in six weeks!!! I'm absolutely losing the plot after five months... it's beginning to affect my mental health... most days I'm so upset by this situation and I have no kids but at the point of asking for a hysterectomy... no one is listening to me asking for further investigations or tests to find out what's going on.... I'm always refused ! I'm also considering getting a solicitor involved as it's taken 5 months of absolute fighting with my GP and specialist to get any where ! Does anyone have any suggestions where to go or what to do or what to try to stop this bleeding I'm at my wits end!! I've tried complaints to practice managers which go unanswered! I tried the health secretary, I've tried contacting the patient Liaison service nothing gets answered....
