Has this happened to anyone?? Leaking fluid but not amniotic fluid 🤔

I’ll be 39 weeks tomorrow, got out of the shower today, COMPLETELY dried myself, went to put my pants on and gushed water all over the floor. No color, no odor, definitely wasn’t pee so second thought was okay, my water broke. Dried myself, cleaned the floor and did the cough test, leaked more fluid. Called my L+D they had me come in, did a swab it was negative amniotic fluid but I definitely had fluid coming from somewhere. Put me on the monitors, I was contracting but not enough to say. Doctor came in, did a swab, negative again, saw fluid but not much. Fluid in the ultrasounds were good and baby was happy as a clam. I’m 1cm (barely) and 50% effaced. Sent home with no answer as to what exactly the fluid is but to keep an eye on it.

Anyone else ever experience anything like this?
