FedEx refused to help me with heavy packages, not sure if I should complain or let it go.

I’m in security and work access control for my building’s loading dock. The shelf for packages is on an elevated platform above the dock bay; there is a small set of stairs someone can go up to reach the elevation. The FedEx guys often just throw the packages on the dock, so whoever is doing access control has to lift them up. I just entered second trimester, and while I’m not “showing”, I’m still not supposed to lift above 20-25 lbs.

The first round of packages was fairly heavy, I barely managed to pick them up and place them on the shelf. I asked if he could bring the next ones up the stairs; he ignored me and placed another on the ground. I asked again, and he took out his headphones, laughed and said “why?!” in a condescending tone. I told him (in a similar tone) I was pregnant and needed help with heavy packages. He tossed the last one at my feet (so I had to pick it up) and left.

I’m admittedly pretty moody, so I can’t tell if my anger is justified or not. Is it “not his problem”/job to take 10 extra seconds to carry the package up, or was he in the wrong? My boss reminded me I can call him or the maintenance guys to help if need be, but there might be days I’m working alone on a weekend and won’t have that option.
