Newborn cluster feeding then...

Okay I have an 8 day old and super confused on her feeding needs. There are times she goes 2-3 hours and now at bedtime I have to wake her up cause she will go 4+ hours. And then at least twice a day she will cluster feed like crazy for example right now I started feeding her at 12 she fell asleep feeding so I woke her up burped her and she burped up a lot and

Wanted to continue to eat. She

Kept eating till 12:50 to then burp up need a changing and now we are feeding again at 1:05 😫 is this normal? I am just concerned she isn’t getting what she needs I know I am producing enough cause the milk catcher I use for the opposite boob she feeds on catches a minimum of 2-3 oz per feeding.
