Help please is my waters leaking.

Ok b4 i start i am truly sorry if I gross anyone out but not sure how to describe. I am 35 weeks tomorrow few days ago I noticed a jelly like snot when wiping then 2 nite when I got up from couch and walked to kitchen I got a trickle of water run down my leg. Now I'm wondering if it was my mucus plug and if my waters are leaking. With my dd I was started at 37 weeks as they noticed she had stoped growing and I had reduced fluid but I didn't realise I was leaking then and she had breathing problems when born and spent 2 weeks in nnicu. Really don't want that to happen again.

Ps dd is only 11months old now so wondering if bein so close it will make things happen sooner. Gonna have my hands full.
