Clomid has more side effects and will thin out your lining. You may want to check on price. Clomid is pretty cheap, but from what I hear Femara is pretty pricey if not covered by insurance.
Whichever you choose, make sure you are doing monitored cycles!
SO, just doing to reading on Femara, it's used for Breast Cancer, and says not to be used by premenopausal women... How is that ok to be used for this then?
Also, Is temping enough? my OB lives 4 hours away and I just can't drop everything and keep going back to have it monitored.
Here is a really good explanation about how femara works:

The monitoring is important...especially the ultrasound. If you are only doing the cd 21 blood test, then the only thing you know is if you ovulated or not and what your progesterone levels are. Temping will only tell you what day you ovulated on.
The ultrasound will tell you the other things you need to know:
number of follicles (do you really want to chance having many follicles and risk having multiples? or what if you are aiming for 2 follicles to increase your chances but you are only getting one?)
lining (your lining needs to be 8mm+ for implantation to occur...what if you are doing all of this and it turns out your lining isn't thick enough? clomid really has an effect on your lining)
size of follicles (you may be ovulating, but are they mature follicles?
if they grow too big, then they turn into cysts instead of egg follicles)
cysts (cysts can be very dangerous if they aren't detected...they can burst or continue to grow)
At the very bare minimum, get the monitoring done for the first few months to see how your body reacts to the drugs.
