Changes in Stuttering Patterns?

Changes in Stuttering Patterns? I don’t know if this has happened for anyone else but recently I’ve noticed that the way I stutter has changed. I’ve stuttered for most of my life and it’s been a repetition like over vowel sounds like “a-a-a” but now I’ve been experiencing a lot more blocking where just no sounds come out. Also I’m noticing I’m starting to stutter more when I’m talking with family members and close friends and even sometimes when I’m just talking to myself (those are more rare) it’s been strange because I’m 18 now and I’ve gotten better at my fluency but I’m not sure if it’s because of the pandemic stress or what but I’ve noticed those changes. Anyone else?
