Breastfed newborn poo

Theresa

My newborn is 1 week and two days old.

He is only breastfed.

He passed his meconium on his second day, 2 poos were done. He did a third poo on his third day. Today marks exactly a week since his third poo.

He hasn't pooed since. Should I be worried?

I have a midwife check up today and I will bring it up. I just wanted to know has anyone else experienced this?
