Jen,
Your this sickness same as me when I first find out I pregnant and I was so sick like you, can't eat, can't sleep, whole body so weak and my high fever really scare me, increase daily till 39.8, doctor even suspected I got SARs at the point of time. After all the check, not SARs, not degee fever so he just told me is virus attack and i was on bed for 3 weeks cos I refuse to go to hospital during peak season of SARs.
