Does walking and exercise still bring on labour if the head is already engaged ?

I am 39 weeks and terrified of being induced! I just had my mw appointment and she said LO head is fully engaged, everything I've read about helping bring on labour has said exercising to bring the head down; but I'm guessing that will not help now at this point ?

If anyone has any coping tips for the last stage that would be great also as I'm very impatient and all set up and can't sleep from the excitement of waiting for my little one !
