worried about my baby

Heather • got our miracle on the way after 3 Yrs trying 2 ectopic 1 chemical and 1 m/c

So my baby is 9 days old and hasn't pooped since Sunday night I feed him every 2 hrs for about 30 mins he pees plenty just isn't pooping. He doesn't cry like hes in pain from not pooping or anything is this normal?
