Nausea so bad

I am only 6 weeks and I already cannot stand the constant nausea. Using sea band bracelets, saltines, ginger ale, peppermint tea. Bought preggie pops but theyhaven't arrived   yet. Nothing helps. On top of that I have a cold and my stuffed nose is not helping. I haven't thrown up yet but I know it's coming. I am a recovered bulimic and throwing up now terrifies me.
