Hi Nightingale, sorry only just found this forum. Yes, ureaplasma. I too had it and DH and I went on 2 courses of AB's before it cleared.
The premise of ureaplasma is that it can cause miscarriages and possibly failed implantations, and it's worthwhile getting it treated just in case. On the other hand, a number of the fertility places don't look into it as some women have it and manage to conceive.
I looked at it from the 'let's do as much as we can' to prepare for our transfer and throw everything and the kitchen sink at it (we have used our last frozen emby).
Definitely get DH onto the AB's when you do - it can be spread from one to the other ..... Good luck for your next cycle
