Have felt nauseous for a few days. Haven't eaten a full meal in a week. Every time I start to eat I get a few bites in and feel sick. I haven't been sick yet but keep getting the too much saliva feeling iykwim.
My head hurts, I'm knackered and my back keeps aching. Boobs feel fine and period due Friday (fingers crossed!)
When there's not too much saliva my mouth feels really dry.
I just want to eat a bloody turkey tomorrow 
Does this sound like a bug? Also having heartburn if I try to eat which I've only ever had in late pg.
