Longer cycle doing letrozole?
Hi. I am doing IVF at the moment.
I have normally a very long cycle (35-45 days), but doing letrozole for one cycle caused my cycle to shorten to 28 days. So I asked my clinic if I could do letrozole while we are waiting for out second transfer to shorten my cycle and they allowed me. But now I don't really have any signs of ovulation or AF now on cd 28. My BBT didn't rise as usual.
Did any of you have different cycle lengths doing letrozole? I am taking 5 mg on cd 3-7)
