Can’t tell if she likes me?

I have a new female coworker that has been working with me the past few weeks. Within the first few days she found out i was going out of town and asked if I wanted to meet up with some female friends of hers. I declined. Then a few days later she asked if I wanted to go for a walk during lunch we did and talked for a little while l. Then a few days later I asked her to lunch with me and we had a really great conversation for an hour. In between these interactions she has teased me in a flirtatious way smiling etc. I don’t really know her that well yet, but am I reading too much into this as she may have interest in me or she just a friendly person?
