Alah, jangan panik lah mama, fully breastfed babies boleh go longer without pooping, especially after 6-8 weeks, sebab breastmilk is highly digestible, so some babies only poop once a week or even longer and it's completely normal! Since your little one is wetting nappies like usual, perut tak kembung, aktif, and nursing well, likely dia okie je, tapi honestly if it's been close to 5 days and you're worried, boleh check with the pediatrician just to ease your mind, a few of my mum friends were in the same boat and the doc reassured them immediately, so no harm asking!
