Yes..definitely see if they'll do a full fit for you! I'm 5'4" and the 47cm Trek WSD was actually too big for me! I was test riding a 51cm Specialized because I could stand over the top tube (compact frame) and when I asked the shop if the 44cm I ordered would be too small, he showed me how my reach measurement compared to the top tube/stem combo measurement. I truly needed the 44cm...even with a long torso (I have short arms).

There are just WAY too many options to eyeball it! After riding for a year on a bike that was much too big for me, I cannot emphasize enough how important fit is...
