Preterm premature rupture of membranes?

Is any one else on bed rest because of preterm premature rupture of membranes? I had my water break at 16 weeks 5 days I am now 18 weeks 4 days, my OB has me on home bed rest until viability (24 weeks) & then I will be admitted into hospital bed rest until induction.  I feel like all I do all day is research pprom and get anxiety over every little twinge in my body! I can't focus on anything! It's been a hard couple of weeks so far! & I have a feeling it's going to be a pretty long, stressful journey!
