Antibiotics and morning sickness

So I was just starting to get over my morning sickness a bit and I got put on an antibiotic and now I’m constantly nauseous and puking way more than before. It’s made me have zero appetite and I basically feel like I have the flu, I’m unable to eat or hydrate (especially hydrate) enough. Please give me anything that’s helped you in this situation, I have 2 more days of antibiotics to get through and it says I could feel this way for another 3 days after that.
