Water leaking?

I’m beyond frustrated :( I had several gushes of fluid and so I called the doctor and they had me come in to get tested. And even the doctor said she’d be surprised if it was negative for fluid. But some how it was negative. Is there anyway this could be wrong? I’m more than positive it wasn’t pee as it was clear and gushed more than once and even the doctor said she was sure it wasn’t urine but not sure what it is then. I’m just so heartbroken and genuinely worried that they just sent me home without really checking anything else.

EDIT: it was my water rupturing! 💙
