Diarrhea for 2 weeks

My almost 9 month old was sick last week, I took her to the dr and she said she just had a cold. I thought the diarrhea would stop but another week she still has diarrhea. Sometimes up to 3xs a day. Like once a day then the next day have a soft pass then the next maybe like 2 diarrhea and so on. But 2 weeks of it. Should I call her dr again? I’ve limited baby food once a day or sometimes she dosnt get it but she’s drinking formula
