leaking?

hey i need advice!

i’m 33 weeks tomorrow and these past 2 days i’ve been leaking a lot of watery discharge with increased back pain. with my first i went to l&d and got checked and it was a bacterial infection so i’m wondering if maybe it’s that again? i’m in the middle of switching insurances and doctors because we just moved across the country so i’m just wondering if i should go into l&d to get swabbed or if i should just play it by ear? how can i tell if it is amniotic fluid? thank you!!
