I suggest you to read a book called "self therapy for stutter", its available as pdf and I can send you a link if you want, also you can practice different techniques and rules mentioned in the book in the stutter discord server, I did the same thing and noticed a different in my fluency, there are 3 block correction methods in the book which are pre-block, post-block and in-block corrections so you have to practice these to see if they are effective or not.
