Do you think I blew this job interview?

I just had an interview i was very nervous for. It was going OKAY but at the end she was like "I'll call you in 2-3 days" then she said something else I didn't catch. I asked "what was that last thing you said?" She seemed real weirded out, and was like "have a nice day?" She then laughed and said "I had to try in remember what I said lol" I felt like such a moron walking away, and like I totally blew this opportunity.
