Need a suggestion whether what I did was right or wrong

So there is a girl I like in college but I wasn't able to talk to her because I didn't want to create a scene or let people judge her(we are from different depts)

Finally I got a chance to talk to her but I don't know why I cracked a joke which I don't know should have been done because we were talking for the first time(btw she laughed)

So I think I fumbled my chance so should I clarify it and approach again so should I leave it
