As you have already given these medications for 8 days and baby is not improving you should take your baby to the hospital and get her tested too so that you will know the exact problem with her. I understand that you are apprehensive about going to the hospital but doing nothing about the problem can be more dangerous. Continue breastfeeding the baby with precautions.
Next Steps

Health Tips
measure the baby's temperature every 6 hourly and look for any danger signs of fast breathing, bluish discoloration, not feeding well.
