Delayed milk coming in

Has anybody experienced this? I have a one week old baby and my milk really hasn’t come in yet. The pediatrician has me supplementing baby with formula and wants me to exclusively pump right now to get my supply up. Has anybody ever had this and their milk eventually came in? Or was it that your milk never came in and you couldn’t breastfeed? I am feeling so discouraged.
