Baby not pooping?

Erin

This is my second baby but first time breastfeeding. She is 7 weeks. How often should she be pooping? For a while it was after every feeding, then once or twice a day. Now she hasn’t pooped for 5 days....I’ve read several different things and I know I can call her doctor but before I do I wanted to ask you lovely ladies ❤️ she doesn’t seem too uncomfortable, just at some points she seems to be.
