You really need to visit your GP or Gyno ASAP!!
This could very well be nothing but if you are having unprotected sex, this sounds like chlamydia. Don't be overly shocked or upset- it's very easy to diagnose and treat, a smear like test and anti-biotics. But left untreated it could leave you infertile.
Your partner will have to be tested and if appropriate, treated.
Good luck!!
