All in all a bad shed isn't something to 'stress' over. A soak or two and it's easily handled, but maintain the humidity levels at 50-60% will help you avoid most bad sheds.

As for the pics... it seems like it's more of a burn. Belly rot usually looks more rusty, but not bloody. What type of setup do you have? If you do not have anything controlling the heat source, then it's very possible you have a burn. I'd recommend getting to a qualified herp vet as soon as you can. In the meantime, I'd work on correcting your husbandry issues by using a thermostat or a dimmer to adjust the heat output and a digital thermometer to measure the temps.
