Femara

Anyone have any success getting pregnant and in Femara? I am 10DPO after a medicated IUI cycle with injections. My husband has "sperm" issues.  Monday they take a blood test to see if I'm pregnant. The day after my IUI my insurance sent a letter that it wasn't covered. The office is writing it off as I already had my procedure but they said I had to do oral meds first.. So I'll be going backwards. Anyway I've done research on the injectables, clomid and Femara. Femara is the only one that states that it "can cause birth defects" this makes me very nervous...
