If a girl cancelled a third date because she had a "cold," is she worth pursuing? Should she initiate the raincheck?

We met through a mutual friend matching us up. We first contacted/met through email, and her responses sometimes took nearly a week. We met twice, but the second date she was late and at the end of a nice dat she said she needed to think about another rendezvous I suggested. I followed up a day before that third encounter, and she happened to be sick, I guess.
