help?

I have a question. So, I'm 16 , I'm very tiny. I also wear tampons. Well, my cramps are literally the worst , they're so bad that I've blacked out before. I read it could be that your tampon can touch your cervix ( like a penis can ) which if I put my finger up there I can touch it , so I believe my tampon could. Basically my question is , if my tampon touches my cervix would it hurt more than regular cramps and could that be the cause of why mine ar so bad ?
