Randomly started stuttering recently and have no idea why

Randomly started stuttering recently and have no idea why I’m 16 turning 17 in a few months and for some reason like a week or two ago I just started stuttering. I used to be able to hang out with my online friends over Discord and talk perfectly but now I’m stuttering every few sentences. I just get stuck on a word and just start repeating it and I’m just confused as to where this stuttering is coming from. I don’t have any brain trauma, don’t take any drugs or medications, currently not stressed, no one else in my family to my knowledge doesn’t have one. Can you guys help me on this cause the last thing I needed in life right now was a random stutter. Thanks!
