Did I mess up Valentines Day?

My boyfriend and I are in a long distance relationship. I have been so busy with school that I totally spaced that tomorrow is Valentines Day. I didn’t send him anything. If I were a guy I could very easily call the florist and get some flowers sent to him, but since I am not what should I do? Do you think it would really matter? Should I just call and tell him Happy Valentines Day, or would that make me a bad girlfriend? I feel as if it is already too late to do anything about it.
