I was going to ask that exact same question, since I withdrew from a school after less than two months, although they don't have a med school to apply to.
If you were enrolled in the course long enough so that you had to withdraw from your courses (not just drop them) - about 2 weeks for my school - then yes, you do.

Easy answer - call the school, ask if they have transcripts on file for you. If they do then yes they need to be sent. If they don't then no, you have nothing with a recorded W and don't need to.
