Cervical cancer symptoms

Hi there, I am a 22 year old female , I have had bleeding after sex for a few months now and pelvic pain. Bladder issues etc. I got a smear test which came back with HPV positive and abnormal cells on my cervix. I have my colposcopy next week. I had sex last week and since then I have been bleeding very heavy (worse than a period)

Was anyone else the same with cervical cancer ? I know I am very young but the abnormal cell changes are concerning my doctor! 
Thanks in advance x
