First professional job interview, how should I go about it?

First professional job interview, how should I go about it? Hi everyone, I have a job interview in a couple hours, and was wondering if I should disclose my stutter when we’re introducing ourselves so it doesn’t catch the person conducting the interview off guard. My stutter is Bipolar, some days I will be almost completely fluent, some days moderate, and other days I sound like I’m completely unable to formulate sentences, so speech on my end will be a flip of the coin type or deal. If you guys have any interview tips, let me know please!
