Getting a second date? Be persistent?

I went on a date last Sunday and it seemed to go well. Decent physical contact, sharing food, never a silent moment, she asked a lot of questions about me and i did the same, etc. But she rejected my kiss at the end. The next day she thanked me for the date. I responded with "hey I had a great time and would def like to see you again. Let me know when you are free next week" I haven't heard from her and its now Saturday. Is she not interested? Should I ask her out again with more specific plans or wait a little longer? Although I'm 24, I've never had to pursue someone so this is new to me.

So I texted her to ask if she had plans tmr, and that I wanted to take her out. She responded saying a friend from her home country was visiting her and she'd be busy this weekend and week. In her text, she apologized and put a sad smiley (does that matter?) I told her "no problem!"

I'll message her next weekend to try again. Might as well persist until I either get her or she rejects me,
she didn't have to respond or give an excuse, so that counts for something right? lol
