What is this!?

We stopped nursing a month ago. Since then, we have switched formula 4 times. She is now on Nutramigen since Friday. She is having diarrhea. Her diapers have been pretty seedy but today this was in it. It’s thicker not like mucus and was a string. I tried to pickup with a wipe for a picture but failed and it balled up. I’m getting concerned. Her little lady bits are so raw from the diarrhea!
