breastfeeding/ pumping problem?

ive noticed that whenever i pump my right breast, i dont get any milk, but if i do its very little, and when i breastfed my son on my right side, he acts like he is still hungry after a feeding. and he's fine on my left side, and when i pump my left side i get enough milk out. Is this normal? cause i feel like its not. And can i do anything to make my right side produce more milk?

I'm not really sure. See if you can find any info on kellymom.com. It's a great BF site!
