normal poop for a 3 week old formula fed?

Elizabeth

hey glow family looking for some advice. My little girl is 3 weeks old and is fed 95% enfamil gentleease and like 5% boob because i dont produce enough. she usually poops about once a day but she just went 2 days without pooping and when she finally did go it looked like this. Its 2:30 on a Sunday morning here in buffalo ny. should i call doc today or can it wait until monday? or is it nothing to really be concerned about? thanks.
