"Horrible pelvic exam"

I was told to go straight to A&E after seeing my gp as I had an extremely painful bartholin cyst that was bleeding everywhere and I could barely walk. After waiting over 6 hours I finally see the gynaecologist who, without any warning at all, shoved the specula inside me and prodded the cyst until I was almost in tears to which she commented 'oh does that hurt' (yes.. why else would I be here?) before continuing to apply pressure to it. Afterwards, I was covered in blood and just told to put my trousers back on. I understand that this exam was necessary and would cause discomfort, however I am only 18 years old and this was my first ever pelvic examination and I would have appreciated some warning of what was going to happen as I left feeling violated and shaken up. My mother was in the room and was also shocked that they gave no verbal warning as well. I am terrified of ever getting a pelvic examination again it was a horrible experience.
