I loved Femara (I've used it all ;)) I had no side effects on Femara, felt like it was a very 'natural' cycle...no increased mood swings, no intense ovulation pain, etc.
I ended up getting pregnant on a natural cycle, but still credit Femara with 'jump-starting' my body ;)
The only thing that was a bit unique for me, from what I've read on posts, is that I took ALL my Femara pills on CD3.
