When someone loses a limb does the body eventually compensate by producing less blood? If so, how long does it take the body to do so and where does the excess blood go?

perhaps a stupid question, but I would imagine with the limb gone your body would require less blood in circulation.

Yes, somebody with a missing limb will have a smaller total blood volume.  Just like in any other person, blood volume is mostly regulate by the kidneys, which respond to changes in blood pressure and electrolyte concentration by retaining or secreting water.  When the limb is cut off, all the blood in that limb is lost, as well as any blood lost during the process.
