Just wondering if other peoples' stutter behave similarly

Just wondering if other peoples' stutter behave similarly So, I don't know anyone with a stutter, so this is really my only outlet for similar experiences. My stutter will fluctuate regularly, about every 1 1/2 to 2 months as I've noticed. It will fluctuate in terms of its severity. Some months I will hardly have a stutter and I'll take every opportunity to speak in class and to my friends as I can get. And then other times it will be so bad I'll be stutter almost every other word. It will also fluctuate in terms of what sounds I will stutter on. Some months it's f, s, and t sounds, other months it will be b, d, and r sounds. So I'm just wondering if other people experience that same fluctuation in their stutter.
