Purple nipples while pumping?

Christine • Mama to a 6 year old girl, 1 year old boy, and pregnant with #3 due 2/3/20💕

Does anybody else’s nipples get suuuper bruised looking while pumping? It goes away super fast and they go right back to normal. I told my lactation consultant about it and she just said she’d rather have them be purple than white! I already tried turning the suction down but they still come out really purple. Is this normal?
