Very attractive female coworker has a crush on me…?

A different coworker that I am friends with told me a few days ago that a female coworker has a crush on me. She gave me her number and has been texting me. Work has been awkward.. It just caught me off guard. I have never been with a woman or even thought to.. but I am not completely against it seeing as I identify as pansexual but like I feel so odd and awkward? Should I get involved? When I get a text from her I just feel so weird… what would you do?
