My DS was a femara baby. I did about 5 cycles of it and then was pregnant with him. We tried femara again to get pregnant. I was pregnant and it ended in miscarriage. Two months later I was pregnant again and am now currently 12 weeks. This time I am on metformin as well since I have PCOS. I think the combination of the two has helped me this time.
Femara works for a lot of people. It typically creates less follicles, but it can result in multiples (this pregnancy started out as twins), but less of a chance than injectibles and many people overrespond to injectibles.
