clogged milk duct?

I haven't had my baby yet but I'm 32 weeks and my left side is producing colostrum like a champ like to the point where I have to hand express a little bit to keep my nipple from feeling like it's going to explode off my body. However my right side is not producing near that. I might get a very small amount out after one squeeze but then that's totally it... I don't know if for some reason my right side just isn't producing or if I have a clogged duct. My nipple never hurts over on that side like it's full and if it's not producing what can I do? I already eat oatmeal everyday, take my vitamins and stay hydrated (all of this because I plan to exclusively breast feed and want a very healthy supply) it's just not producing or it's clogged. Has anyone experienced this before and what did you do if anything to fix it?
