'Limited activity' can I still work?

As
I just got discharge at the hospital (all is well, dilated to a 1, 40% effaced) and was reading my paperwork and it talked about how I was allowed to get up and use the restroom, shower and other 'light activities'. I'm on pelvic rest now too I guess. does this mean I can't work? 95% of my job is standing and walking (retail). I'm going To call in the morning but I was curious if anyone else knew anything.
