My baby drank poopy bath water

Okay so no mom shaming. I already feel horrible. My lo (19 months) pooped a little in the bathtub and before I realized it she drank a little bit from her rinse cup. 🤦‍♀️ There was no poop in the cup, but of course I’m sure it was contaminated. I’ll keep an eye out to see if she gets a fever, but has anyone ever had experience with this? She’s fine right now, but I’m going to call her doctor in the morning.
