im pretty sure after a few weeks ur body kind of recycles the fluid anyways so u should be producing more, but if ur concerned u need to ask ur doctor. hope all is well.
Yes, I heard of a woman whose water broke at 24 weeks and with bedrest and good nutrition and hydration (and i think also antibiotics?) she made it full term. Good luck, hun! I can't imagine how stressful this must be for you.
With complete bedrest and drinking lots of water to help replenish fluids there is a chance. Good luck
