UPDATE. TMI. my daughters diaper

it looks like blood and mucus to me. Am I right ? Please help me out in figuring what I should do. I'm freaking out. Thank you 
UPDATE: to those who are wondering I took the diaper to the pedi but she didn't want to see it. She basically said it's something I might've fed her. She prescribed some vitamins since I'm breastfeeding and said it could also be my breast milk. She also looked at my baby's privates and said everything looked fine and that we were good to go.
