Maybe you should call and talk to your doctor or emergency room. I dont think anything majorly bad could happen but it really wouldnt hurt to talk to a professional about it and make sure that if you did swallow it then it wont hurt your baby or you.
I'd definitely talk to your Dr, how big is the bar? Because if its not too big it will probably be OK, just talk to your Dr to be safe!
The bar was a little less then an inch
