need-some-advise

Hello all, my name is tanya and I'm 14 weeks with my first child.

i need some advice please.

the past week I have felt very nauseous, not been sick but I can not even think about food. I have managed to eat a croissant yesterday and a few lightly salted crisps but that's it. I now have an upset stomachs and feel very weak. I don't want to be one of those paranoid first time mums calling the doctor but I am a bit worried now. 

Any advice you Gould give would be very helpful.
