bfp after clomid?

I'm out this cycle after getting a call that I haven't even ovulated. So I have to see my dr once af starts and I'm pretty positive he's going to tell me the next step is clomid after several failed femara cycles. 
This is so hard, and I'm in need of some hope. 
How good is clomid?
Any of you had success with it? 
Any of your advice and experiences with this would be very appreciated..
Thank you
