Femara Questions

Hello ladies!
I just today stumbled onto the Assisted Fertility section.  Love it. I've been married since 2003; off BC since January 2007; and am 38 years old. I've had no pregnancies.  Started monitoring my days closely a year ago actively trying to conceive. Nothing yet.  Just saw a fertility specialist who wants me to take Femara. 
Has anyone taken it before?   Any suggestions or comments?  
Thanks and best of luck to all of you! Xoxo
