You met her on a dating app. That's 100 percent a date! See if rescheduling works. If she bails again, you opt out. Dating apps are tricky for everyone! No one says who they really are. Why would they? Everyone puts their best foot forward and it is only when you meet in real life if you get to decide whether or not you like them. I think in order to calm your nerves, don't be so worried about her. You think about you. Do you like this person? Do they make you laugh? Does their moral compass aline with yours? Are they allergic to pets, etc. And, definitely add that you stutter to your profile. It weeds out the people who won't be right for you from the beginning. Remember, stuttering is a part of you. It doesn't define you!
