Heppened to me too it can happen without feeling it the babys on your bladder.
This exact thing happened to me two years ago and drs sent me home I believed the drs and for a weeks I kept leaking fluid and after a week I finally started having contractions I want to the hospital I had an emergency c section and I lost my baby bc it set up infection in the amniotic fluid.. If you continue to experience this go back in and demand a second opinion better to be safe than sorry I was 34 weeks when it happened to me I wish I would have know the things I know now trust your body mama you know what you experienced. .
You might be potty trained but the baby can push down on your bladder in a way that you might not notice it but can cause you to accidentally pee. I've done it a couple of times and a hydrated person has clear urine. So it was possible to be pre but discharge it just as likely.
It was probably just a discharge. The tests are unmistakable.
If the test came back negative then it weren't ur water. Could have been discharge. Mine sometimes is clear ans watery.
