Should i take propranolol for the upcoming ielts speaking test?

Should i take propranolol for the upcoming ielts speaking test? I am not a neurological stutterer, i just stutter under anxiety. I’ve read some reviews in this sub about the medication and i think it could potentially help me. Can any professional in pharmacy help me about this? I could really use some advice right now since 3 days from now will be my examination. To be more particular, i am 17 and is a male. I am frightened by the fact that my stutter will drag my score down i won’t be able to acheive my dream score.
