Can I catch this ureaplasma in time before another miscarriage with the antiboiotic zithromax 1000mg one dose and have a healthy pregnancy? I get ureaplasma all the time so is one dose even going top work? Both me and My husband keeps getting it and we get treated tge antibiotics before use to kill it for a couple months then come back now it seems as if its not going away which a few times we did have sex on the 6th day of the treatment's which we was told to wait 7 days. We are waiting 14 days
