Mucous plug? Water break questions...

I am 32 weeks and 5 days. Last night i went to the hosptial because i swore my water broke. I had a giant gush of fluid come out when i stood up from bending over. It seemed like way more than urine but all tests for amniotic fluid was negative... Is it possible to have a gush of fluid but then nothing or did i really just pee myself? Also, later that night i had 3 rounds of bloody mocous come out of me. I did have a cervical check at the hosptial hours prior. Could this be just blood from the cervical check or am i loosing my plug? Labor and delivery are non helpful nurse saif she doesnt know and thinks it is normal but to monitor it...
