Hi Morgan, perhaps keep her upright for a good half hour after each feed and keep shifting her into different positions? Sometimes just the shifting is enough to produce a burp.
On the poo thing, its really the wet nappies you want to look out for. If she's weeing, she's not dehydrated so you can know she's getting enough milk. As MR said, there's no such thing as normal with baby poo-frequency! They could go ten times a day or once every ten days. As long as they're drinking and weeing, they're fine!
GL with everything! (And congratulations on your lovely new little bub )
