Water breaking?

Ophelia

Felt two sudden gushes like discharge had come out, so I checked my pad and it was just wetness. Then I sat on the toilet and a bunch of fluid gushed out. It looks like cloudy water?

FTM and I have no clue what water breaking is supposed to feel like but I’m 37+5 weeks. Haven’t had bloody show or anything but have had a lot of tightness and pain in my back and lower pelvis region today.
