A girl who gave me her number said she'd call me back. How long do I leave it?

Friday just gone i was out for dinner and a girl working there was really flirty with me. I ended up getting her number (she even favorited it on my phone). I sent her a text the following morning and didn't hear anything that day. The next day I called her in the evening and asked if she wanted to meet for a drink. She said she had plans with friends early this week and she'd call me back. She asked where I was based and when I told her, she said we could meet in the middle. She didn't sound unhappy or irritated that I called. Admittedly I'm not great at picking up signals or reading in-between the lines. What I'd like to know is how long do I leave it before I either leave it or text/call her again. I'm a little confused because even to me she was really flirty with me infront my parents and favorited my number. Any advice would be great, Thanks.
