1st time mom question!

Hey ladies. So I'm a first time mom and as everyone has I worry about everything. My baby is 5 days old and my pediatrician told me that my baby should be eating every 2-3 hours and having 3 poops and 6 pees. She has been good so far but today I've noticed she hasn't pooped just yet (while it's still early only 11am here) I know there is plenty of time. Since midnight she's already peed like 3 times so she's half way there. My pediatrician said to call if she isn't meeting those bowel needs.  Clearly I have to give her time to go throughout her day but if she hasn't pooped by tomorrow you all recommend to call right? Like I'm not over thinking this.
