What are the side effects for Juvederm Volbella in lips?

I rec'vd 0.8mL Volbella in my lips in July - I never planned this, but was receiving therapeutic botox & the Dr recommended I plump up my 'ageing' lips. I've never ever considered filler, but acted on impulse & I now stress about possible side effects all day everyday. Have you had much experience with Volbella, and has it caused granulomas or other issues in your patients lips? Can pregnancy hormones affect filler & cause reactions? What is the average time it really lasts in your patients?
