Should I contact the girl who gave me her number and what to say (description below)?

So there's this girl I like and I think she likes me as well (it seems she is giving me signs like trying to talk to me and create eye contact but I am not 100% sure). So today I saw her and as a joke asked if I could get her number thogh she probably knows I already have it and she just took a piece of paper and a pen out of nowhere and wrote it down for me. Now, we haven't been talking too much in real life, so I don't know if I should text/call her, and if so, what to say? I'm not really good at those kind of things
