membrane sweep??

Kyla
Ok so I've been seeing a few post and articles on it. I'm 39 weeks exactly with my 2nd. I'm oh so tired of being pregnant at this point and last week appointment I was not dilated at all 🙄
With my first daughter I was 4 centimeters by this time!!! I was also induced due to her being in distress. So my water was broken and I was given meds to jump start labor. 
So my questions are...does it hurt? Is it effective? How long does it usually take to start labor? Should I even bother getting it done?
