I know when I was on clomid I was told not to take EPO and the same for the FertilaidCM which I really felt I needed as clomid took all my EWCM away. I don't know about femera sorry
I have read/heard variuos things about this topic. My conclusion was that since epo effects your hormones that I wouldn't mix it with femara. I think they might contrdict one another ?
