Does anyone else have occasional stuttering?

Does anyone else have occasional stuttering? Hi there. I'm bilingual. I'm fluent both in Finnish and English. But sometimes when I speak in English, I start stuttering. It doesn't happen always, it's very random. Does anyone else have this kind of selective stuttering? I wonder what exactly happens to me when I stutter. I feel like maybe I feel more nervous when talking in English, since it's not my native language. Maybe that nervousness of correct pronunciations causes stuttering? I wish there was a quick fix for this.
