FTM & labor

So my mom and grandma had all their kids late so I'm guessing this means I'm more likely to deliver late too. Does anyone have any ideas on what I can do to prevent my baby from staying in too long? I'm not trying to make him come out early or anything I just don't want to be induced and would like him to come out sooner than 41 weeks. I've heard walking, sex and nipple stimulation which I've been having sex but haven't done the other two. I'm currently 35 weeks and 2 days I'll be 36 weeks on Monday and I see my doctor next on Tuesday so I'll talk to her a little more about this as well.
