So I am 22.5 week pregnant and I've had a terrible cold/cough for almost two weeks. I went to the doctor today and she suspects it is whooping cough (despite having been vaccinated). She prescribed a z pack for it. I was updating my friend and she freaked and told me not to take it bc they are dangerous. I know the doctor looked it up and said it was class b, but now I want to check. Any other pregnant moms ever take a z pack before?
