Any exclusive pumping mummies here? Do you bring along your pumps and where do you normally pump if you're out by yourself almost the whole day? (exclude working place)

I pump b4 going out, but that also means i have to come home earlier to unload milk otherwise will engorge. Unless i bring bb with me to latch on me. If going out the whole day i confirm will experience engorgement, so i will definitely bring my pump
