Has anyone here heard of Ureaplasma?

I’m 24 weeks with ureaplasma but my doctor prescribed me ANOTHER round of antibiotics but this time with erythromycin (i’ve taken azithromycin twice but it made me throw up so much) and i’m scared to take it because I don’t want to throw up again. I’m not sure if I can take it with milk.

it also concerns me because of how it will affect baby, and if it’s not working anyway. Has anyone had or has Ureaplasma? or had a success pregnancy going natural? Leaving it be? Please let me know, I honestly just want a healthy baby and that all that matters to me. 😔
