Hinge date updated profile after 3 dates

I (23M) have been on 3 dates with a girl (23F), and things have been going really well. On our second date, she said she liked what we had, wanted to see where things went, wasn’t seeing anyone else, and wanted to take things slow. Before our third date, I noticed she updated her dating profile, but I brushed it off since we weren’t exclusive. On the third date, she said she was too busy to see other people and asked how I’d feel if she did, and I said I’d be disappointed. Since then, we’ve been talking regularly, and she says things like “I really want us to work out,” but also “whatever happens will happen.” We have another date coming up, but I noticed she updated her profile again. I’ve started to really like her and haven’t been interested in anyone else, so seeing her still active on the apps has left me feeling disappointed. Am I overthinking this, or is that a reasonable reaction?
