PPRom at 18 weeks

Erika
So I'm on bed rest since I ruptured at 18ws (currently 19+5w), I just wanted to see if there was anyone else out there like me. 
Any suggestions to keep infection away until I get to 24 weeks at least when I make it to the hospital bed rest? 
I just want my little man to make it. I have my first HR appointment on Thursday and I'm not sure what is going to happen either. 
Thank you guys.
