Waters broke?

Last night I was getting in bath and a gush of water came out making a puddle around my feet. I think got out bath 30 mins later and a smaller gush happened. Then I called my midwife she said put pad on and lie down for an hour if u get up and it comes out call the labour ward so I lied down for hour got up and fluid keep coming out. I called them they told me to come up for a check. I went up there and they said they couldn’t tell if it was my waters or not but the test came back negative for it being my waters. They told me to go home and contractions could start in next 24 hours and if they didn’t i have to go back today at 6 to have another check and if it’s positive been induced today. What is going on has this happened to anyone else the colour is yellow tinted but it was clear at first so idk if it’s just urine or not but it’s still happening 16 hours later so if it’s not my waters why am I constantly peeing myself after I stand up. (I’m 39 weeks today)
