I just wanted to say Pushy that although bf is the natural thing to do, this does not mean it is necessarily easy. It's a learned skill, for you and your baby, and this can mean it takes time to get it right. Unfoturnately for some mothers it's much harder than for others. As Barb noted, you're doing lots of extra work right now, so well done on keeping it up!
I ended up using nipple shields for a time as, despite seeing LCs and working on it very hard, we just couldn't get the attachment quite right. It all came good after around 10 weeks - now it really is easy.
Don't worry if you have more milk on one side or the other - it really doesn't matter.

I hope things start to improve soon - good luck
