Im 10 weeks pregnant and tested positive for Ureaplasma, Im so worried from everything I read online. Im on Zithromax 5 day dose.. and I just took it also about two weeks ago for a sinus infection... Will my baby be ok. Ive read that most doctors dont even test for it and its very common, but also miscarriage and birthing an unhealthy baby at 20 weeks is typical. I'm so afraid. Please help. ANY advise would do some good.
