Goodbye Clomid Hello Letrozole

As expected I was told that 100mg of Clomid had not worked yet again, during the ultrasound the nurse asked yet again if I have been diagnosed with PCOS. (Do they even read my medical notes ??)
She then explained that my lining was at 5mm which is a little better than before but still too thin and my follicles were not mature at all.

I then waited to speak to the nurse about my next steps and was surprised to find that it was one of the fertility specialists doing the follow ups this time. " Horray! I can ask some questions " sprang to mind.
He explained again that the increased dose of Clomiphene had also not worked and said that he was changing it to Letrozole (commonly known as Femara) to see if that worked. He also asked about the aspirin and how that was going, so I told him that I have been taking 75mg a day and stopping during the week of period as directed by the nurse. The doctor was shaking his head at me "no no no" he said and then told me that I should I fact be taking them every day continuously and double the amount from CD1 to CD14.
I was quite annoyed with the fact that I had been miss informed by the nurse previously because in my mind something like that could be a contributing factor to why the treatment hasn't been working.
But hey ho, it's done now so I just have to forget that and start again with the new medication.
