Nope.

or is that a sign to call the repairman ?

Sure, or have a peek yourself.

I noticed a good amount of water, I can't tell if it's from when it
went off
balance. I wiped it up, did a regular load, and noticed a few drops
on the
floor.

A fairly quick way to narrow down where to look for a leak, place a
sheet of cardboard under the washer ( it should be almost as big as the
washer ) and run a short cycle. When the washer is finished, look for
the stained/wet spot on the cardboard, this will help point you in what
direction to look for where the leak is coming
from...front...back...right side...left side.
