It's totally fine to have intercourse on days 3-7 while on femara. Sometimes they ask you to abstain a day or two before ovulation...to help increase the sperm count for the big O...but other than that, you can have intercourse whenever you want while taking femara. Best of luck this month!
I don't understand the ???, you may not ovulate that early but I don't see why u wouldnt be able to have intercourse throughout ur cycle....
