Pumping at work

My bf and I are TTC. I plan to breastfeed exclusively. When I go back to work after maternity leave, I'm worried about pumping at work. I work in a small office with one other woman who has no children, and seven men. Truckers come in and out all day for their paperwork. There are two bathrooms for one and the other and I realize I have the right to breastfeed at work- none of these people would make me feel weird, but I don't feel comfortable pumping in a bathroom several times a day. Is this something I'm going to have to learn to 'get over' or is there a way for me to pump " a lot" before and after work and be ok?
