Hospital bed rest. .. any info/experiences appreciated.

Whitney
I have been diagnosed with vasa previa and one of the recommendations is hospital bed rest at 30 weeks and constant monitoring. Has anyone ever been through this? I mean, can you still walk around the hospital? Take a shower? Wear your own clothes, or always hospital robes? Sorry, I'm sure I sound ignorant, but I have no clue what to expect and just want to be prepared if 5his actually happens. Thanks everyone!
