These antibiotics are killin' me 😭

Ive been on an antibiotic for 3 days now because I was told I have bad bacteria from the cultures they took at my first OB appointment.

I was FINALLY getting my morning sickness under control before that but now I have a TERRIBLE metallic taste in my mouth, I can't even drink plain water it tastes so bad 😭

Its making me nauseous because I can't snack every few hours because nothing tastes good and I keep dry heaving for what seems like no reason.

I don't know what to do 😭😭😭

Has anyone experienced this before?? I need some advice!
