What to do after getting her number [College]?

Met this girl at a career fair and I decided just to walk around with her and meet other companies with her. After we got done I asked for her number to stay in touch. She asked where I parked at and I told her I take the transit bus. I then asked her if she wanted to go eat at a sandwich shop with me on campus and she said sure. I buy her a meal and we share fries and I ask her about her family, hobbies, etc. I then asked her if she wanted to walk around campus and she said sure and then asked her if she wanted to go to a school club with me on Monday and she said she has to check her schedule. I then told her I had to leave and then we departed ways with her saying “ I’ll let you go now” This was Thursday and I haven’t texted her and was wondering should I just wait to see if she hits me up on Monday about the club or should I hit her up right now to hang or chat?
