Nipple stimulation to bring on labour ? Has it worked for you ?

Anna • Mother of two beautiful little men
I am using my medela swing pump on each breast for 15 minutes. I still haven't had a contraction... what am I do wrong ? I was 2 cm dialted and fully effeced... when I was in preterm labour on the monitor my contractions were really strong but I didn't feel them .. does that mean Ill have a silent labour 😕
