BFing twins: Brewers yeast pills or fenugreek?

Madison💁🏼‍♀️ • Retailer// Married 6 yrs// Mommy to fraternal twin girls// surprise baby on the way!
A little over 2 weeks postpartum and My supply needs help and I'm feeling discouraged. I ordered fenugreek tablets but I see many of you take Brewers yeast pills and have lots of success...
Should i take fenugreek or Brewers yeast? Or both?
