Should I wish luck to my crush before the exam, if we haven't talked for about 2 weeks?

About 3 months ago I texted the guy I like, that we should go to get coffee sometime. He agreed and we kept in touch through text messages for a couple of months. He used to always text me first.Then we went on a date and everything went quite well. After that date I've heard from him a couple of times, he texted me first too. But the last time we talked, I did text him first and after that we haven't talked for 2 weeks. He has an exam tomorrow, he told me about that on our date and I am wondering if I should text him good luck. I don't want to sound like a creeper, who remembers every single detail, but I don't want to fall out of touch too. My girlfriends thin it would be cute to do that. But what about you guys?
