Need of cycle buddies to get me through this ttc.

Renee
Hi my name is Renee. I am ttc #3. I am 40 yrs old and me and my husband have been ttc for a year now. My af is due on 6/18 and I am hoping and praying it don't show up. I have been going to see a obgyn Dr to seek some help. They are going to put me on clomid. Does anyone know if it works because I did research online and they say Femara works better any suggestion?
