Just a help for a peace of mind

Hello my baby is almost 5 months and she has been having diarrhea for about 10 days. I did sent her to the doctor he says you just need to wait for the 14 days to be completed. She tested negative for bacteria. She lost a bit of weight but she is getting fed normally. I am really worried that maybe the doctor is mistaken and afraid that the condition will last. Does anyone have a same experience as I do?
