it depends on the risk/complication.
others are really recommended to just lie on the bed to prevent preterm labor.
in others, it means reduced activity, or magrelax-relax muna. you may stand/walk for sometime. yes, you can sit.
ako nun 32weeks spot no pain. pinagbedrest ng 3days with pampakapit for 1week. sa bed ako kumain, higa or upo lang. lalakad lang if maligo/cr. tpos sa ligo nakaupo lang din ako at mabilis lang.
