when to start Mothers Milk Tea?

Elise

So i’m 36w5d, i want to EBF, but in the past i had a hard time with my supply, i never did anything to try and help it either so this time i want to start mothers milk tea, when should i start it? Can I start it while still pregnant? Also,

I’m being induced next weekend due to preeclampsia so i’m not gonna be pregnant much longer.
