FWIW, I used zofran and had a perfectly healthy baby. All options are worth discussing with the midwife/OB. I had hyperemesis with DS, so I was admitted with around the clock IV nausea meds/ fluids. My doctor actually told me it was better for me (and baby) to take the meds. I am taking Diclegis now and it is helping a ton. I can't function without it.
AFM, I have a scan Friday and "graduation" from the fertility clinic!
