burning white sage

Brittany
Has anyone heard of burning white sage to induce labour? I've been taking EPO for two weeks now. Bouncing on my ball. MW said it was all definitely working. 
I couldn't sleep last night so I decided to cleanse the house with white sage, two hours later I was woken up with terrible contractions starting in my back only on the left side and they wrapped around to my front left side, paired with the tightening and loosening of my whole uterus. I'd love to know if the sage brought this on. I'm currently 38w+6d
