Welcome to Android Central! That's a tough situation. The backup PIN is there for just this reason, so it's important to remember or keep in a safe place. You could try using Android Device Manager to reset the PIN, but I'm not sure if that works when you're on fingerprint unlock: https://support.google.com/nexus/answer/3388218?hl=en
