uneven production?

Meredith • Mother to my rainbow baby girl 10/21/16 and 1 on the way due 1/4/19 🌈🌈
I feel like my right breast isn't feeding my daughter as well as the left. When I pump, the production is about the same but when she nurses she seems so be struggling with the right. Also the left seems to be getting visibly larger and fuller. Similar experiences?
