Was my doctor flirting with me? or was she just being friendly?

Ok, so I went to an eye doctor, she's pretty attractive for her age.

Anyway she asked me a couple of questions, she found out I was a student and asked what I was studying, I told her I'm trying to be a personal trainer, so she nodded and subtly looked towards me, I think she was looking at my arms or core area.

Later she said I've got "nice big pupils", and then she kept bumping my feet, and after 3 times of bumping them, she apologized lol.

So after I went to the desk to pay, she stood like 5 feet away from me, crossed her arms and looked at me. then went away, wtf?
