6 weeks preggo today and soooooooo nauseous!!!

So I'm tired of ginger ale and crackers and toast!!! Is there anything else I can do for nauseousness?? Please help!! This is my first pregnancy and I have no clue. My cousin told me to take "Zofran" and I googled it and on fertilitycenter.com (in the FDA part I guess) popped up saying pregnant women shouldn't take that. Again, this is my first pregnancy and I don't wanna take anything that'll harm my little blessing!! Any suggestions??
