From a first time mom who has had NUMEROUS supply issues I am here to tell you that not everything works for everyone. I have had supply issues from one side especially and I have tried everything and I still have to supplement at times. I have tried the herbs fenugreek and blessed thisle and have found that they seems to work very well at increasing it a little but not to where I get more than normal. When I pump I normally get maybe 2 or 3 oz out of one side (the "helthy side") and 1 to 2 oz out of the other side (the one that has not worked very well from the beginning). Plenty of sleep, water, and no stress if helpful.........but not always available when you are a new mom.
Hope this is somewhat helpful and good luck. Just remeber whatever you can give your baby as far is breastmilk is best so just give what you can.
