Boobs uneven

Jennifer
I'm exclusively breastfeeding my son and he normally eats every 2-3 hours... I'm usually starting on one side and nursing for 15-20 mins and finishing and the opposite side for 10 mins and then start on that side the next time... But I'm noticing I'm producing more on my left side than the right how can I get them to even out or can I even get them to even out at this point?
