What does it mean when a girl looks at you in a coffee shop untill you walk out, and didn’t look away when you noticed her?

I work in a building where there is a coffee shop on the entire ground floor, I walked out of the elevator and headed to the door of the coffee shop, where I noticed a cute girl looking at me. She was cute so I looked at her back and I thought she was going to look away but she tried to look away then immediately looked and stared at me for about 15 seconds till I’m the one who got shy and looked away. I saw her again when she came out but she was wearing sunglasses so I don't know if we had eye contact at this time. She doesn’t look like the shy girl type at all, please don’t get me wrong I don’t mind this type of girl, but is there any chance she thinks I’m attractive? Or she looked at me by mistake and didn’t want to look away? Should I try to talk to her tomorrow? (Saw her at the same time twice in 3 days )
