Where does your stutter occur most in a sentence?

Where does your stutter occur most in a sentence? For me, it does happen at the beginning, but it also happens in the middle of sentences, which makes no sense to me. I’ve been reading about neurogenic stuttering, and the differences of it between developmental stuttering (what we normally associate with a stutter). I’m just curious to see if anyone else stutters a lot in the middle and even end of sentences as opposed to always at the beginning.
