Spotting at 11 weeks

So I woke up this morning spotting a little and I called the doctor talked to a nurse but waiting on a call back from another doctor. I have a home Doppler and everything sounds fine but I'm just worried about miscarrying. I have to work in a couple hours, and I'm on my feet for 8-9 hours a day with little to no break. I don't wanna go into work and make this worse... but I also don't want to leave my boss in a tight spot. I'm trying to get another manager to cover my shift but she hasn't responded. Any suggestions?
