My water broke 21 weeks

Update: well I'm home which honestly I didn't think 48 hours ago was even going to happen with my baby girl still thriving in my belly doing perfectly okay. I am to take it as easy as possible but still able to go back into work until I'm 24 weeks at which point I'll be admitted into the hospital hoping to keep baby girl in there for as long as possible. Thank you for all your kind words. We still have a very long road and literally have to take it day by day.

So here I am at the hospital because my water broke. Has anyone else been through this? Right now it seems like my only option to terminate my pregnancy bc the doctors say i won't last till full term and the risks of having her even at 24 weeks is so slim. I'm just lost?
