Welcome to Just Answer! It looks like your lab work is actually good. I have known many women who have elevated liver enzymes while nursing. It is the abdominal pain that seems to be concerning. Does it increase or change after eating? Does it diminish after taking the digestive enzymes?
Your diet is excellent. However, do you get enough probiotics? Either in capsule form or through diet (such as kabucha, kefir, raw milk, etc)? Also do you eat meat, chicken and/or fish? Your pain in the LUQ signals either stomach. spleen, or pancreas problems. If the pain does not go away, I would recommend you get your amylase and lipase rechecked in a month to keep an eye on your pancreas. I would also recommend taking a break from exercising for a week to see if that has any effect.
