I normally don’t turn down wings...🤮🤢

So I don’t know exactly when I ovulated but AF is supposed to be here in a week. I’ve been having cramps and feeling a little nauseous on and off. Well today some coworkers and I got wings for lunch. I literally gagged at the smell of them and could only eat one and a half🤮 & I’ve had this constant metal taste in my mouth all day and at some times it tastes like blood. I feel like it’s way to soon to take a pregnancy test. But has anyone else had these symptoms?
