Odd-smelling burps during early pregnancy

Does anyone find their burps different during early pregnancy? My burps used to smell of the food I just ate, but not anymore. It has been a strange metallic smell that has nothing to do with the food I ate earlier, for the past two weeks or so. Currently at Week 8 of first pregnancy. It has gotten so bad that I actually gagged from the smell of my own burp 😅😅😅.
