Left vs right

SN
So my left breast seems to not produce more milk. At least compared to the right. Yes I know my daughter will get more out than a pump, but in 20 min my right breast will pump out at least twice as much as my right. Aria normally is on my right breast for 30 min and 15 min on my left breast except the last couple feedings where I had her go for 30 on the left. Anyone know how to get my left breast to produce more and quickly??? Also how to get rid of stubborn clogged ducts. Mine don't wanna just get massaged or sucked out...
