Ummmmm weird smells that aren't even there?

I keep smelling spoiled milk! I DONT EVEN DRINK MILK??? There's no dirty dishes, no spilled milk anywhere? Nothing!! I don't know where it's coming from but it's making me gag and I haven't had morning sickness/nausea in weeks and now I just keep puking because of the horrid smell.. anybody else smell things that aren't real?
