Is it okay to show a bit of vulnerability early in the relationship?

I met this girl twice in a meetup group and we had sex the second time we met. I asked her out on a movie date and then she will come to my place. She agreed to the movie date and coming to my place. It is been 5 days since I texted her and during these 5 days I didn't text her at all. I texted her yesterday to let her know that I bought the tickets. And asked her about the weekend. I am not playing hard to get but I just want to save this for our date that's why I dont text. Our date is 4 days from now. I truly feel that I miss her. Does it look weird if I randomly text her I miss you. Thanks
