It does seem to vary so much depending on your caregiver!
For my first pregnancy I was seeing a homebirth midwifery team consisting of one CPM and one CNM. When I got to 41 weeks, 5 days, the CNM stripped my membranes and gave me the homeopathic version of blue/black cohosh (sorry I can't remember the name) - this got labor started and I delivered my baby about 18 hours later (41 weeks, 6 days). I actually had a non stress test and U/S (to check fluid levels) scheduled for the day I ended up birthing my daughter. Oh, and I had an acupuncture appointment scheduled for that day as well, with the goal of getting labor started. I ended up cancelling both of those appointments With that pregnancy, I found that most of the stress around hitting the 42 week mark came about because of the situation for homebirthers in my particular city -- had I needed to transfer to a hospital during labor, there would have been very few "friendly" options available to me after 42 weeks.
This time around, I'm living in a different city so I had to find a new midwife. During the interview process, one of the things I got a feel for was the "post dates" issue. I ended up choosing a midwife who is very relaxed about this topic. I don't expect her to automatically make a big deal out of it if/when I go past 41 weeks (and I assume I will).
