Why won’t this baby come?!

I am 40+3 and I am MISERABLE! Nothing I am trying is working to help this baby come out. Went for a 3 mike walk last night, bouncing on my exercise ball, eating spicy foods , ect. And still nothing. I get contractions they get about 5 min 30 sec apart for about 25 minutes and then they back off 😩 so frustrating! Just when I’m about to call the OB they stop altogether. Any suggestions to get our baby out faster we are really growing impatient!
