I was recently referred by my GP under the cancer pathway because of yellow discolouration of my cervix and post-coital bleeding.  I had an examination done at Gynaecology and they were happy that it was fine and sent me for ultrasound just in case. I had the ultrasound external and internal last week. I haven't heard anything, then received an appointment letter for this Friday for a hysteroscopy/biopsy. I don't know why unless this is normal procedure? Or did the ultrasound pick something up?
