tamofen

Has anyone's RE used tamofen? I've done 6 rounds of Clomid up to 200mg a month, 6 rounds of femera and 6 rounds of injectables menopur and gonal f. I do ovulate on my own but this was all in hopes of getting the golden egg which after 2 years and 3 months I have not gotten. I can get pregnant 8 times in these past months but my issue is holding a pregnancy. Nothing is wrong with me. No abnormal test other then my right tube is blocked but I had a tubal reversal so I'm not shocked. My fsh is 9 and my amh is 1.60. So my RE said I can try 60mg of tamofen cd3 through cd7. Has anyone done this?
