Hi ladies I've just taken my first dose of 7.5mg letrozole.... I conceived my son 3 years ago on 2.5 and then was upped to 5mg as I didn't respond to another 2.5 but follicles were just a tad too small on 5 so now have been increased to 7.5. In slightly nervous taking this amount. Has anyone else been on this dose and found it effective?
