Is it appropriate to start reading "what to expect when your expecting" and baby development books while ttc?

My husband and I have been trying to conceive for 8 months now. This week I started reading "what to expect when your expecting" and thought nothing of it (we are trying for a baby I want to be prepared when it happens). My husband however saw me reading and made the comment of "Why are you reading that your not even pregnant yet?" Is it weird I'm trying to study up while we wait for our bfp???
