Letrozole help

Desiree

So, I just took my first dose of Letrozole. My Dr. gave me instructions, but honestly it was soooo much. Is there anyone out there who was taken it and could help me? My Dr is out and the staff isn’t really being clear. I know I’m supposed to take it on the 3rd day of my cycle, I have a sono scheduled for day 11. When are we supposed to have intercourse?
