Food aversion

So has anyone had an extreme food aversion really early on? Before you even had a positive test? This will be my fourth baby (possibly) but I've never really had strong food aversions. We've only been trying this month and I'm at least a week out before being able to test. Tried to eat CHEESECAKE and almost threw up. Told my husband that it tasted like raw/spoiled meat and/or really strong iron taste. He ate half the slice and said it tasted fine. Tried another bite later on just to see if I was crazy and almost barfed again.
