Hi All. Just wondering can anyone who has used Letrozole before provide any information on differences they noticed between their natural cycle and their cycle on Letrozole. I am current 2 dpo of my first Letrozole cycle. I usually get sore breasts from the day before ovulation until about 7/8dpo. This cycle I have had no sore breasts yet. I’m wondering if this is due to my hormones being a bit more balanced than they usually are. Has anybody noticed differences like this between their natural cycle and their cycle on letrozole?
