measuring big

To mommas who measured bigger did you go into labor before your due date? If so how much sooner? Had our 33 week appointment today with an ultrasound baby is measuring 2 weeks larger, so 35 weeks. There was no talk of moving up my due date and I don't have GD or any other medical conditions, just seems he's going to be a giant. He is also already head down midwives think he's too large to worry about him turning anymore, thank goodness. The reason I ask is my husband is best man and i am on the brides side in an upcoming wedding Sunday October 30th. I'm a little worried as it's over an hr away and obviously I'll be doing tons of standing and walking. I would  hate to go into labor at the wedding. Talk about embarrassing 😣 But being preparer I'm thinking I should pack my hospital bags with us just in case.
