Sick when eating?

Kourtnea • Mommy to 1 sweet little girl. Trying for my second and last baby. Hoping for a boy but would be excited and proud either way.
I feel fine all throughout the day but it seems like everytime I eat or smell food I get nauseous. Its not time for my next period yet because I am still ovulating according to this cite. So I'm not sure what is going on with me. Any other mommy's have this problem? Is it possible to be pregnant already even though I just had a period 2 weeks ago?
