Glad it went well! Yay for having a plan.
As for TI vs. IUI - I respond well to Femara (on my 3rd month) and we have a great sperm count, which is why we are doing, and will continue to do, TI. My RE said that at their hospital, IUI is not done unless you're AMA, have low sperm count, or have other factors that require more aggressive treatment.
What we know right now is that I don't ovulate (or release follicles) on my own, so we're treating that. If it continues to fail, we'll look into more aggressive insemination techiniques, such as IUI. I also have PCOS.
