Hi there!  We have been TTC #2 for 19 cycles, and I have been seeing a fertility specialist since December.  I have had 2 losses during that time, neither of which was while on any fertility treatment.
So far, I have had an ultrasound which diagnosed PCOS, the majority of my cycles monitored, 3 cycles of clomid (including cycle monitoring for all/ultrasound for one), and just recently an HSG.  I went back to my specialist last week to follow up, and he has given me a script for 2 more rounds of clomid, and after that, the only thing he is offering is IUI which I can't afford.
With my PCOS I seem to have a really mild case.  I still have regular cycles, and ovulate ok on my own.  With the clomiphene cycles I have done, I reacted beautifully to the drug (50mg) but still didn't get pregnant - hence the HSG.  They managed to unblock one tube during the hsg, the other shows an abnormality and they aren't sure if it is blocked or not.  I am trying to feel confident though, as the one they unblocked is my left, and all 3 of my pregnancies have come from my left ovary.  Hopefully thats a good sign.  
All the best with youtr treatment, and I am hopeful that we will both be pregnant soon.
