if you are breast feeding yes that is normal.. as long as she does not seem to be in pain... just keep doing what you are doing.. if she is pulling her legs up and acting extra fussy, then i would call the ped! good luck , and congrats!
Newborns are very irregular. A BF baby can go up to a week without a bowel movement with little concern ( a growth spurt may cause baby to use every last drop of breast milk with little waste). A bottle fed baby can go a couple of days without concern. If baby doesn't seem uncomfortable...then don't worry about it.
