I just met my Work oisiate?

we work in 2 different areas but we have talked on the phone to each other while at work, and she jokes and i make her laugh... we finally met today for the 1st time, i worked on her laptop and we talked alot about each others lives.. she played with her hair, kept stoking it and would pay attention to me speak. My question is, should i wait till after the weekend to ask her out or ask her today... Thanks
