I went to the club last night with a couple friends, had some drinks, and met a girl I matched with on tinder. From even before I recognized her she looked like she was confused but she was with her friends and upon recognizing me she approached me.  I asked if she would like to dance and she said yes. We danced for a bit and I asked if I could kiss her. This is where I became very confused. She either said "no" or "oh" because there was a pause and the music was loud. I assumed she said "no" because I didn't hear a "yes" so I just kept dancing but 2-3 seconds later she turned around and started to kiss me. This had me confused and I'm not really good at reading signs so I asked if she would like to keep dancing and she said yes. After another 10min or so of dancing/kissing I felt she was uncomfortable and I told her I was going to meet up with my friends and asked if she would like help to find her friends as she didn't know where they were. She said "no" and I said "have a good night" and then I left. I don't know why she may have been uncomfortable. I don't know if that was just her general demeanor or not because from the second I saw her (before she saw me) she looked uncomfortable to be in the club surrounded by people. I should mention that I am almost certain she wasn't drunk because she and her friends were going to the bar when she saw me and the drinks were particularly cheap so it wouldn't make sense that she would drink before. Also I didn't smell any alcohol.

I asked her afterwards if she was uncomfortable at all last night but have not got a response so I left the conversation at that. Did I do something wrong?
