advice on preventing labor..

My husband is in the navy and is at a school about 8 hours away.. I'm 35 weeks and my due date is on the 30th. He is scheduled to come home the 24.. I was really bummed about it but I just really don't want to go into labor before he gets here. I know I can't do it alone. If I do happen to go into labor early they will let him leave and he will drive straight up but still worried he would miss it. Any advice to try and push it off.. I would hate for him to miss it.
