Pumping help

Ka

So I'm exclusively pumping for my twins and need some help increasing my supply. I trued the breastfeeding pills on Amazon that had fenugreek in and it ruined my milk supply. I've been eating oatmill and have been trying to drink as much water as possible. Are there any other foods or something that will help increase supply? Also I've been pumping almost an entire ounce more from 1 breast and was wondering what I can do to even it out?
