Baby inhaled water in the bath?

Katrice

So earlier I gave our 3 week old baby a bath and she was squirming and screaming and while I was pouring water on her chest I accidentally poured some into her mouth and i think she inhaled some of it as she was screaming. It's been at least 12 hours but I just noticed my baby coughing and I have no idea why. I'm worried about dry drowning. It's 6am here and my pedi doesn't open until later in the morning what should I do?? Should I be worried??
