Anyone ?

Hey guys, on the Wednesday the 28th I went for a doctors appointment & the doctor gave me some bad new and said I have a complete placenta previa & put me on complete bed rest. Now lately I haven’t been able to do anything. Like I walk and feel a lot of pressure and very heavy. I keep feeling like I’m gunna end up having this baby any now. Like I just got back from a family’s bbq and I just feel the pressure and heaviness real bad. Little back pains. Should I wait , is it normal to feel a lot of pressure and heaviness ? I feel like I’m cramping here & there. But I have no bleeding or anything
