There isn't anything that will help with nausea while you are pregnant, however saltine crackers and cinnamon tea will do the job. I learned that after experiencing 24/7 vomiting with my oldest daughter for 6 straight months. I older lady told me to do that and it worked for all my pregnancies, I would have wished I had known that for my first.
There is no "safe" medication to take while pregnant. Tylenol has been given the "ok" But PLEASE do not take any over the counter or non over the counter drug while preggo.. If you can't stop vomiting Please seek you OB There could be a potential Problem!
Im sorry, Hopefully your nausea will go away around 4 months...there are these lollipops you can get at Motherhood...also try sucking on peppermint. For some reason when I would eat an apple and/or popcorn it always helped mine.
