Med free or Anti-nausea

Kirsten
So my doc has had me on unisom and b6 mixture for morning sickness. I seemed to be coming out of the worst of my sickness once I hit 10 weeks, so I stopped taking it for a few days. I thought it would be better for the baby to not use drugs of I could help it. Well I puked once yesterday and have had two episodes of vomiting today as well as a loss of appetite. My question is, is it better to not take drugs if possible, or is it more important for me to take the meds and be able to eat and hydrate?
