Do you think I messed up? ?

I was texting this girl earlier and asked her if she had seen a certain movie. She said no, and then I changed the subject to asking her about when she wanted to study for our exam (we have a college cl together). She responded with Mon/ Tue and I asked "so both days" and she didn't respond back. We had been talking back and forth before I asked about the movie. Did I make her upset by not asking her to see it?
