36+5. Blood. Tmi

Elizabeth
Yesterday I had blood in my underwear and called my dr they said "it's probably your mucus plug."
I knew they wouldn't care even though I had my daughter at 36+5 and two miscarriages since then.
So today, I noticed light brown discharge in my underwear.
Probably still the mucus plug, right?
I don't want to call my doctor because they don't listen. I've had plenty of problems this pregnancy (including preterm labor) and they just don't care. I had to go to a different hospital to get labor stopped at 28 weeks.
Any advice on how to get labor moving now?
