Anyone ever heard of it? Had it?

My doctor just called yesterday to put me on antibiotics for it. I had some polyps removed last month, and I think that pathology report came back with this diagnosis. We're in our first IVF cycle about a week away from egg retrieval. I'm having a hard time finding consistent info on what might have caused it, especially what the "chronic" part means and how it might affect this cycle.

Hoping to hear some stories of "it worked out ok!"
