cervical cancer

Sorry everyone im absolutely terrified and im looking for advice and i don't feel anyone is taking me seriously including my doctor. For the last two years ive not been able to sit comfortably on my bottom due to the pain in my tail bone, had a colonoscopy every ting came back normal, i then started suffering with frequent urination in September 2013 and has been on going since then. No infection, not pregnant as ive had the implanon inserted in january 2014. Had a high vaginal swab and no sti or infections. Alot of discharge daily, changes from clear to thick plus im nineteen years old. Sexually active with one partner. I get frequent pain inside of my vagina with spotting only when i wipe its clear red fluid not so much a period and it comes on and off. When im sexually active my vagina hurts before and sometimes bleed after but not sure if its down to partner being rough, sorry about too much detail buy im really frightened. There's cancer on my mothers side as my grandparents died of throat cancer and bone cancer.. The pain in my vagina and tight feeling in lower abdomen comes and goes aswell as massive migranes that make me physically get sick and these come once in a while, i dont smoke or drink and i walk everywhere. Can anyone please help me or give me advice. I'm waiting on appointment from an orthapedic and scans and stuff from urologists but in the mean time im suffering terribly please can anyone help with advice. I want to make an appointment tomorrow with my doctor but as im only 19 im afraid he wont let me have a smear test as i have mentioned it before. I feel like he doesn't take me serious and looms at mr as if im making it up. Any help i would appreciate i have nobody to tall to about this only my boyfriend
