Help!

So im a regular poop checker (weird i know) for my one year old daughter. I know what her normal poop looks like. My husband and i ended up taking her to the emergency room yesterday because her poop was stark white,chalky clay like, and very bloody! Doctor was alarmed but did no tests on her. We got home and she pooped white again, with blood. They told us to bring her her if she kept doing it. Fast forward to this morning she pooped! It still looks very clay like, with just a bit of bloody mucus but its still a palish yellow! Should i go ahead and retake her in? Everything im seeing is pale and chalky is bad!
