Is it possible to develop a stutter out of nowhere?

Is it possible to develop a stutter out of nowhere? I’ve never really had any problems with stuttering but within the last few months, I’ve noticed that it’s been a tad bit hard to speak. I would mess up words, finding myself, unable to say what I want to say, even though I know what I want to. I also tend to repeat words, letters, or syllables 1-3 times or unnecessarily draw them out. I’m not talking about normal people speaking when you might be nervous it might find yourself stuttering a bit, or when you miss pronounce a word or some thing and you might repeat it just because you don’t know what else to say. Is it possible or could it be something else?
