Taken off of work.

I’m only 33 weeks, and I’ve been out basically on bed rest. I’m only suppose to stand an hour with 20 min breaks. I work 12 hour shifts in a factory with no sit down jobs. I’m still a ways out from my due date, and I’m just worried that if I apply for personal leave of absence it won’t get approved. I had one of the worst weekends, everything(even down there) was so swollen I couldn’t walk. Lots of pain and pressure in that area to. I never had this with my first, maybe just a little swelling. Anyways I’m just a nervous reck and concerned that’s all..
