Ultrasound options should be different when on period
My letrozole rounds always start with an ultrasound on CD3. They are checking that I don't have any cysts and that I have follicles that should start to mature once my period is over. My log gives me options for how many mature follicles and their size which doesn't make sense yet. It also asks for my lining measurement which doesn't make sense yet either because it's still being shed. I'll like to log the number of potential follicles (today I had about 10 on each side and the number of cysts you have which is hopefully none).
