Need help, please!

I have a somewhat newly bought Kanger Subox Mini and have never had any problems with it that worried me, but today, the ohms are jumping from .5 to .6, back to .5 when fired. Is this dangerous? I'm so afraid of blowing my face up! I honestly know nothing about any of the technical stuff. If anyone can reassure me or help, I'd be grateful!
