Is it appropriate to use nursing room to express milk? As i felt/worried other breastfeed moms will think they should be the priority... sometimes felt so embarrassing when walking out of the nursing without carry any baby... ?

For me as a mother who express rather than latch, I think we are equally important. We need to pump out the milk to feed our babies. I do understand the stares and the embarrassment but I am not using for other purpose such as sleeping so I think is ok.
