Cervical cancer

Hi I'm out of my mind with worry. Had my smear test done of Thursday evening I was referred on the fast track there and then. The nurse said she saw a yellowish blister. I have had bleeding on and off but thought it was my age. I'm 50 so put it down to the change. I've started bleeding again. Also the nurse said I had been given the wrong HRT patches. I'm out of my mind with worry I can't eat or sleep. Thank you
