TMI poop

EBF poop question! My little one is four weeks old and exclusively breast fed, up until now she only had seedy yellow poops, but today her first poop diaper was mucusy with a couple small brown/green spots and now second one is the one I snapped a picture of-has a lot more of dark brown/green in it? Baby is acting fine (maybe sleeping a tad more than usual), wondering if I should be taking her to the doctor or if anyone has similar experience and were told it’s fine by doc? Thank you in advance to anyone who takes time to reply!
