As long as there is no blood in it your fine hun x
It gets lost and regenerates from what I've seen. Only if there's blood should you want to get checked!
I’m 30w and lost mine the other day. I went in for checks and they said it’s fine.
Discharge is ok but if you’re worried I recommend contacting your community midwife x
It doesn’t always indicate labour, it can rebuild itself. I’d keep an eye though for any pains, blood etc I’d then go get checked x
