I have PCOS and am overweight as well, so my ob put me on metformin to cause ovulation and a regular cycle. I conceived once, but it was a chemical pregnancy, sadly. My progesterone levels were too low to cause implantation.
My ob then put me on Chlomid, with an HCG trigger, IUI and progesterone. Sadly I heard yesterday that it didn't work (the 2 mature follicles didn't produce eggs which were fertilized). So they did an endometrial biopsy today, in hopes of seeing whether I have LPD (a shortened window of implantation). That is normally fixed by progesterone, which I was on, so maybe they'll get me another higher dose or different application if it turns out that I have LPD.
We're going to try another Chlomid/HCG/IUI cycle though, so hopefully this will be the charm. It really is a brand new world, and I find myself so challenged by all the new language and concepts.
I will be watching this thread, and hoping for lots of happy news for everyone.
