I will be 5 weeks preggo tomorrow and I have been sick almost 24/7 for about a week now and I called my OB because my 1st appt isn't until May 30th. They said they would call me in a prescription for Zofran. I got to Walmart to pick it up and they want $90 for 20 PILLS!!!!!!!! That's WITH my insurance!!!! Does anyone know of a safe nausea med that is cheaper and works? I didn't want to take any sort of drug while preggo but I can't even keep water down! Maybe it's my hormones but this is ridiculous to me!!! Help? Advice??
