I've learned that being open about myself early-on in a relationship avoids a lot of future angst. Other than when I've met people while en femme, I don't think I've ever "dropped the bomb" on a first encounter, but I admire you for doing so. Something about her must have clicked with you on a very deep level to be so open and honest from the start.
My advice would be to give her a call and see where it leads to.
Best of luck!
