I have not heard from her after our second date. Please give me advice. Thank you.

(Ok first off let me start by saying that I do not want any negative sarcastic replies. This is serious to me thank you)

So it has been 3 days now since I have not heard from my date. We have known each other for a good 3 months. and started dating 2 months ago, but it didn't work out. But besides that. We started over and spoke to one another a lot in texts and instant messaging. (shes not a fan of talking on the phone) But anyways she looked like she prepared a lot the second date we went on. She kept checking herself of how she looked in the mirror of her car, etc. We had a great time, she cuddled with me as we played some video games, held hands while going to breakfast, I told her she's pretty, and have nice hair etc and she smiled. she giggled and laughed at things id say that weren't the funniest things. So at the end of the day when she needed to get back home. dropped her off mid point where we meet up. (haven't been to her house yet). we smiled, saying goodbye and hugged her, and we natrually kissed on the lips the firs time, and smiled, soon right after I told her to be safe driving back home and that was it. I hope I didn't rush leaving. People I asked said I didn't f*** up on anything. But I like to ask more people for advice on this. I contacted her a half hour after that moment, and told her I had a great time with her, etc. I know she said she was going to be busy, But that rest of the day I have not received a single text response back. I texted her again that night around 9pm (I dropped her off at 330ish pm) And still no response..the next day I texted her in the morning around 11am saying hi to her with a smiley face. Nothing. Then I asked her if we were going to go out with her friends that she mentioned on the date we were on. But still response, then I sent one more after around 5pm..asking if she was still wanting to do it, and hope I wasn't bugging her. since then I have not heard from her or texted her back anymore. which today now I have not texted or contacted her at all now. and as well as today so far. and no word from her. My sister told me to wait several days. like 4-5 days. and see if she comes to me. she thinks she needs time to get her emotions together, and maybe playing hard to get? People tell me not to worry. But I can't help but to worry D=

Thing is I can tell she likes me. In the texts etc we'd go back and forth with before the 2nd date we'd flirt and bit with each other of what "moves" to make and "finding out" what will happen. So does she like me still? I feel like I'm a bit paranoid over this. And I hate to wonder a lot. I am patient but would like to know what she's doing this. How much longer should I wait to contact her? Wait another 3 days good? I learned from after the first date she doesn't like clingy guys most women don't . so I limited my way of contacting her so much. That's why I have stopped contacting her after the second day. So can anyone help please? I really need the assurance and advic
