I think someone tried to scam me, should I be worried?

This woman recently tried to book me for drop-in visits, but she was very incoherent in her messages, i.e not answering my questions, weird punctuation, vagueness, etc, she said she was "relocating" to where I lived and that's why she needed a sitter. She also asked for my personal number because she said her app wasn't working, I made the mistake of giving it to her. I noticed that her photos of pets were stock photos with clear watermarks on them. I don't think this person was real, but now they have my personal cell number. I declined their request and emailed Rover support, I also blocked their number, but I'm still pretty freaked out! Should I be worried? I don't want to keep working with Rover if this is going to happen.
