Hi lonesome,
Aren't you already "punished" enough? I mean, you have to live with what you did. People make mistakes, that's in our nature. You had the courage to tell your h and to work out your problems. That's more most people would do. You're taking responsibility for what you did, that's a good thing. You don't deserve to SI.
Could you take the test a second time to be sure?
Stay safe
