Moderate changes - Anyone in similar situation

Hi All,

I am 26 and I just had my first smear test. My test results came back as high grade - Moderate.  I am waiting  further tests but I am so scared....

Please if any of you had same test results could you please share your experiences. Is it very likely it might be cancer? I never had any bleeding in between periods... only painful sex sometimes. 

I am very worried. I appreciate all your responses...
