bloodletting burns calories?

This is a rather out there question that crossed my mind. I tried google but came up with nothing.

So, my question is, if you lose some blood, your body is going to make more, right? And wouldn't it need to burn some sort of energy/calories to make more? Like, you can't just make something out of nothing. Do you lose calories donating blood?
