Does jumbling my words together count as stuttering??

Does jumbling my words together count as stuttering?? It happens a whole lot, especially when I'm talking animatedly or just talking to people. Sometimes I have to backtrack and repeat my words more clearly and although I joke about it sometimes it's really embarrassing. I'm not sure if it's an anxiety thing because it happens when even I'm not anxious. Generally, I prefer writing to speaking; I'm a whole lot more efficient at the former. Does jumbling words count as stuttering? I haven't been able to put a name on it.
