First day i feel really crummy...

I'm currently 9w3d and this is the first day I feel like total crap. My face and chest are so hot and flushed, yet I am freezing. My stomach is all over the map. I am trying to finish a 5 hr shift at work and am so afraid I am going to vomit into my trash can. Plus I keep getting dizzy spells while sitting down! Never had this with my first pregnancy and pray this is just an odd day. Thanks for reading, I just needed to share with others who understand.
