so I work as an unloaded/stocker for my job, is that at risk of a miscarriage?

I had a miscarriage in august and I don't know the reason for it, but since I unload and carry heavy items I was curious? Has anyone took a LOA (leave of absence) early in a pregnancy? Considering what job you have of course.
