Dilated - brown discharge. Labor soon?

Amber • always stay humble 💕
Went to my OBGYN and they said that I'm 1-2cm dilated! I am scheduled to be induced on the 18th but there's a good chance I could be going into labor earlier. I noticed brown discharge today - idk if it's because of her checking my cervix or if it's my mucus plug. Has anyone have this happen and then they went into labor right after? Also, what are some things to bring in a diaper bag for when they leave the hospital? Thanks!
