T. - been there done that.
I have PCO - did clomid, no help. They later found other stuff (autoimmune antibodies, blocked tube). I went through 2 assisted reproductive tech. cycles (1 IVF and 1 IVF that turned into an IUI) and have 2 beautiful girls.
Usually after clomid, they'll want to check to see if your tubes are open (Hysterosalpingogram) and a laparoscopy to see if they can aspirate cysts on the ovaries (polycystic ovaries have too many). See if you can do these 2 at the same time to save time, money, and effort. Then they'll want you to wait 2 cycles to see if that helps, and may increase your dosage of glucophage depending on how much you're already on.
After that you'll need to decide about IUI vs. IVF or whatever depending on what all is found after you go to a specialist.
The specialist I went to ran all the tests he knew to run before starting any cycles because we didn't want to get into a cycle and have it fail because something wasn't caught beforehand. That's called "putting the odds in your favor". (and when I went to see him, I was over 200 pounds, and am 5'4".)
If you want my doctor's name, feel free to contact me. I'd be happy to share any info on what we went through and things we did financially that helped.
