Is getting stood up on dates a common occurrence for anyone else?

I’ve recently finally started saying yes to dates after two years of abstaining from dating post transition and I think I’m about to be stood up / cancelled on for third time (out of five dates so far). Am I doing something wrong? Am I unattractive? I really don’t understand why these men are all talk, but when it comes down to actually meeting up, they get cold feet? This is so disheartening, at least tell me before I waste time doing my hair and makeup?!
