This is my 4th pregnancy (one miscarriage) with extreme morning sickness. With my 2 girls, it lasted the whole pregnancy. I was on multiple nausea meds the whole time. Last time, they tried to put me on phenergan which made me too tired to take care of my kids. This time, I had Zofran and they said to go ahead and take it. It worked for a week or 2, and now it doesn’t matter if I take it, I’ve already thrown up probably 10 times this morning. Eating and drinking makes it worse and I’ve tried anti nausea drops and they also make it worse. At what point should I call my dr back?? Anyone experience this??
