39 weeks 5 days still working

Ladies today I called out of work I'm a medical assistant for pain a management office I'm constantly on my feet walking sitting standing and deal with patients especially since I'm manager in the back I always deal with the aggressive patients. but after a long weekend of walking sex nipple stimulation I'm not feeling good at all I thought maybe it is early labor but I'm a FTM and it's hard to tell. Should I throw in the towel and stop working? I feel like a weenie but I don't feel good at all. Any thoughts is this?? unhealthy to be working until 40 weeks ?? Should I suck it up and go?? Should I rest at home??
