Milk flow decrease


My LO is 3 months and for the past 3 weeks, I have seen a decrease in my milk production. Anyone else noticed a decrease?

I have started a regimen of power pumping once in the morning, bowl of oatmeal, cup of Mothers Milk Tea, and 1 Milkflow capsule. For the rest of the day I take 2 capsules, water and Gatorade, and regular pumping every 3 hrs. I hope this works.
