Should I be concerned that my OB never scheduled me for weekly visits?

I'm currently 37+4 and my last doctors appt was over 2 weeks ago. I'm not scheduled for another one until the 16 th and the next one after that isn't until the day before my due date (August 27). Am I right to feel a little uncomfortable with how little I'm being monitored? I have a friend due two days after me and she's being seen twice weekly now by her OB so I'm a little bummed that my doc isn't trying to see me more. I should also add that I was never scheduled for appointments twice a week either, I've only been seeing my OB monthly with sometimes as much as 6 weeks between visits. What are your opinions ladies?
