Really sick

So the last week or so I've been craving Chinese like crazy I've probably dropped like $60 sad but true. And if I eat anything else I get sick . Like I ate French fries like 10 minutes ago and I feel like throwing up although I haven't . And I went down stairs to go see my dogs and let them out side and the smell of them (we haven't given them a bath this week yet and they roll in the dirt so they are stinky) almost made me throw up too.. I did have my period for October (7-12) so IDK if I'm pregnant or just weird? Help?
