Going on my first date ever.

Going on my first date ever. So as the title says, i am going on my first date but I’ve met her two time before this. We have talked but I didn’t talk much and tried to hide my stutter which was not the best thing imo. I want her to know my stutter and support me but now that I’ve hide it, how should i tell her? I’m just scared this might lower her expectations of me or anything. Or i think maybe if I didn’t tell her and then on the date, she will eventually find out my stutter then it will be even more embarrassing.
