Some background on my nursing history as I'm not sure what all is relevant! 
My daughter was always quick at the breast, never wanted to nurse from both sides for each feeding. I also had a very bad oversupply that I fixed with my lactation consultant with block feeding. I'm no longer block feeding and my oversupply is no longer a thing. However my daughter ONLY wants to nurse on my right side. (She's 13 months) I posted a while ago about her not wanting food which isn't changing much other than for smoothies and purée's. We went to the doctor yesterday and she hasn't gained weight since April (19lbs 3oz) and her pediatrician asked me to pump at night for ten minutes then in the morning for 10 minutes. At night I got no milk from the left, and only a milliter from the right. In the morning I got 2 ounces from the right and non from the left. Am I not producing enough milk? Do I need to start up fenugreek and lots of pumping sessions? I'm waiting for a lactation consultant to call me back but I'm freaking out
