I will be 7 weeks pregnant tomorrow. This week, morning sickness hit me hard. I cant keep anything down and it lasts all day and night. I have already lost 5 lb. I called my dr and she prescribed zofran. She said if it didnt help then she would prescribe phenegrin. After receiving zofran, I learned it can cause miscarriage or birth defects. I haven't taken any yet and now i am too scared to. On the other hand, if i cant keep any food or liquids down, my baby could be harmed. I'm stuck. Any suggestions? I've tried everything else I can think of and nothing is working.
