Thanks for your query.
Your baby is having diarrhea
which is mostly viral in nature and takes few dys to settle.
I suggest you to get her examined by pediatrician
(as one of stool samples show RBC 18 TO 20)
regarding proper management.
In the meantime continue with breastfeeding
,oral rehydration solution sip by sip after each loose stool
Give lactobaccilus for 2 to 3 days.
Wishing your baby good health,
