Water broke at 22 weeks and 6 days :(

Bethanna • I'm a mom of 3 and one on the way! :) 2 girls aged 4 and 3 and boy who's 2. We're hoping this little pnut due Is a boy!
Not doing the best :( I was in the hospital for 24 hr observation Monday for water leaking night and sent home. Then yesterday started having cramping and pressure and it was like a scene out of the movies it was a waterfall all over the bathroom floor, and continued until I got to the hospital. I'm now on antibiotics and iv fluids to try and keep her in there as long as possible. Any one who has experienced this before please I'm honestly lost as to what's going to happen to our little girl. 
UPDATE::
Did an ultrasound just now she's still breech and I've only got 2cm of fluid but when I came in there was nothing left. Heartbeat is good. Staying stable in the 150
