Should I tell my teacher about my stutter?

Should I tell my teacher about my stutter? Hi guys. So I have to give a presentation in front of my class in 2 weeks and I'm trying to decide whether I should tell my teacher about my stutter now just to give her a heads up so I don't lose marks or just go and do the presentation and hope I don't stutter. I'm kind of leaning towards telling her but I'd love to know what you guys think.
