Any help or suggestion, please?

Yung 3 weeks old baby ko kasi until now hindi pa rin sya nakaka pupu. Her last poop was May 11 and it's already May 15 today. Yung last poop nya sobrang dami as in tapos basa naman sya after nun di na nasundan. Pag hindi pa rin sya nakapoop today we'll call her pedia na para mabigyan kami sched for check up. First time mom po, worried na talaga ako sa baby ko.
