Darker browner mucousy poop

LO only pooped once yesterday (usually goes 2x) and 4 times today - sometimes a little but this was one of the bigger dirty diapers —- and past week it’s been this darker brown color, looser and not the usual brother yellow - he’s ebf and has been sooo congested because we are packing 🙇🏽‍♀️ is this still normal?
