Taking letrozole twice in same cycle...

Paula

Anyone else? My follicles did NOT get large, CD 17 second time they were checked with ultrasound. One ovary has a 13mm and the other has had a 12mm for the last week that hasn’t grown. Starting today, I’m taking 7.5 mg letrozole for 4 days and rechecking on the 21st. CD 3-7 it was 5mg. Anyone else have it twice like that due to follicles not growing?
