31 weeks pregnant with questions !?

What to pack for labor & delivery.. ? Hi ! So I'm currently almost 31 weeks pregnant and was wondering when should I start packing my labor & delivery bag ? What did you pack/what all should I pack for myself, baby, and the father ? Also, when did you lose your mucous plug, and after you lost it, how long until you went into labor ? Today I started nesting. I went CRAZY on cleaning. Re organized all the babies stuff, cleaned my room, hung up all his clothes in his room. Is nesting normal around 31 weeks ?
