Would like to check is it after delivery, there will be engorgement from breast due to breast milk p

no it’s not automatic. milk kicks in 2-3 days after delivery. first day or so will just be colostrum. some mummies don’t have milk or low supply. if you choose not to breastfeed, need to still pump but not so often. need some time for your body to know not to produce milk. you can ask for medication as well to speed up the process.
