Hi I felt the same way through my whole pregnacy. If you go to your doctor the can perscribe you some tablets that will settle your stomach and you wont feel so nauseas. They helped me. I also found that popsicles helped me not be so nausous. I dont know f it was do to the cold or not. you have to eat no matter what but only take a bit at a time like a couple of bites. I had mornig sickiness from the time I woke up to the time I went to bed I know what you are feeling. You hopfully will get though this. Good luck Also try taking Gaviscon it's for hartburn but it also works for nausea.
Congratulations, and I feel for you. I had terrible morning sickness with my 15 year old daughter and the only thing I could stomach in the morning was vanilla Paddle Pops(don't know if you have them over there, they're a frozen milk type ice block)!
