hydronephrosis? 37 weeks

Any body else have it? The doctors have talked induction at 39 weeks if pain continues but I'm only 37 and feels like I've had back labor for 3 days now I don't think I can last much longer, I guess passing kidney stones is worst than labor but all of my tests came back negative for anything with stones but still believe I'm trying to pass them they just can't see if they're stuck in my ureter but I have increased fluid in my left kidney
