Increase Braxton Hick with discharge

I’m nearly 30weeks with history of preterm births

I’ve been having increase of Braxton Hicks over last couple of days

Last night I had pink discharge

Today no pink discharge but when I get a Braxton hick contraction I’m noticing lots of discharge happens during or admittedly right after

Is anyone else get increase discharge during or right after a Braxton Hicks contraction?
