Working pregnant

Does anyone work at stocking and unloading at Walmart.? Is it hard. I got a offer today for that position but I’m 2 months pregnant n worried about the heavy things. Well I told the guy I couldn’t really lift heavy things n he said it would only be up to 15 pounds and that he wouldn’t put me in the furniture section. Do y’all think I’ll be ok working there. It’s from 5am - 2pm. N also my Dr said that I could lift up to 30 pounds.
