One breast not feeling empty?

Jennifer

For my three pumps so far today, I feels like my left breast (my rockstar breast) isn’t getting emptied. The first two pumps I did pump a lot from it but not as much the other two. I’m not getting a good let down like I usually do and if I change the suction, my nipple doesn’t feel any discomfort (but my right breast does). There’s no pain or hard spots to indicate a clogged duct. My nipple also just feels weird after pumping. I changed my pump parts maybe a little over a week ago but I just ordered more and that’ll be what I do when they come in tomorrow. Any other thoughts or suggestions as to what it might be?
