TMI- Is this normal baby poop?

My daughter will be 7 weeks tomorrow. She was pooping fine the first 2-3 weeks and then she would poop with mucous and now not anymore, pedi wasn’t worry. She’s now been pooping once a day or sometimes goes a day without pooping.

She is formula fed, I’m not producing enough milk to be able to feed her. She was on Similac Pro-Advance the first few days at the hospital and she’s now on Similac Advance through WIC.

Should I be worry? She’s a gassy girl

but doesn’t show signs that she’s in pain. Her next appointment will be next month.

TIA!
