Stutter or no?

Stutter or no? Hi all, could I have your opinion on whether or not what I'm experiencing is a stutter? Over the past 2ish years I've been occasionally struggling with words, by either: - getting stuck repeateding the first word of a sentence, like a broken record. I have to stop talking to move on. - repeating the first sound of a word, like "th-th-th-this" - having trouble physically getting the sound past my lips, particularly m or p's for some reason, it's like sounds is stuck in my mouth but I can't push it out. I didn't have a stutter as a child which is why I'm not sure this is considered one or if it's something else entirely? It doesn't happen every day but can be worse when I'm tired. Any thoughts? Thanks!
