Audit risk in 2016 low 2017 medium should I be worried?

I had 2 sources of 1099-misc income 2016 and only 1 in 2017.  My audit risk was low in 2016 on the Turbo Tax Audit Meter now this year it's medium for 3 reasons, I have a schedule C, Significant reduction in business income from last year and business expenses are significantly higher than my business income.  I also have a FT regular job as does my wife but obviously if I dropped my insurance sales business but kept my online educational coordinator business my income will drop and my expenses for home office will be proportionately higher.  Should I be worried?
