Is talking too fast also a part of stuttering?

Is talking too fast also a part of stuttering? So I have been stuttering for 9 years now at first it was like just repeating the same word again and again (normal stuttering) now it's blocking but in the recent years almost always when I try to say a sentence it comes out too fast for someone to understand and if I try to talk slower almost every word is blocked. Is that a part of stuttering or is it just a different problem I have?
