Nausea?

The antibiotics that I am prescribed for 7 days makes me nauseas and unable to eat.. just what in the actual fuck. Im being treated for a uti at 18 weeks. I have no symptoms so just what the hell why..i was doing soooo good until my doctor decided it was a great idea to put me on these meds.. honestly it is bullshit that I have to go through throwing up again and not being able to eat😡
