Working in a factory?

Jessie • Diagnosed with unexplained infertility and hypothyroidism in 2011. TTC 5+ years. Did IUIs with clomid and letrozole for 2 years. TTC naturally since thyroid levels are on point. Lost 85lbs
Any of you ladies work in a factory? I start my job on Tuesday. It's an ice-cream factory. The labor isn't hard just packing ice-cream. But I'll be on my feet constantly for 8 hours. Any advice is appreciated
