Placenta previa & work.

I went to the hospital yesterday for spotting and got told I have placenta previa. I’m 28 weeks. They put me on pelvic rest & i don’t have an appointment with my doctor until Friday. This is my second time spotting and I guess they’re just now noticing the previa !

I work in a restaurant and I’m on my feet all day, should I be worried about working these long shifts ? With the previa will it be okay ? Anyone been in this position before. Just need advice.
