I think I might be drying up??

So my baby is 6 weeks old. We had a bit of a difficult start breastfeeding but by about 2 weeks we were almost completely feeding without the help of a shield. I’d say at about 3 weeks my left side was so sore so for a day I fed only on my right side and pumped on the left and since then it seems like my left side isn’t producing as much milk despite how much I try to feed. I’ve been starting almost every feeding on the left and skipping quite a few on my right but it seems as thought the right is producing a lot of milk. I can pump about 4 oz just in the right and maybe get an oz on the left (I know you can’t base how much your make by pumping but I think it’s a visual representation of my suspicions.) my question is Can I boost my supply on my left side or is it too late? My baby is gaining weight and seems to be getting full after eating but I’m just worried I won’t be able to continue to breastfeed if I’m not making enough and I really want to not be so lopsided
