ve had 2 failed IVfs. First one resulted
in negative
pregnancy test after transfer of 2good quality blasts. 2nd one,,again 2 Grade A blasts, one attached and resulted in miscarriage at 8 weeks (no heartbeat).So RE suggested genetic testing, which i dont know they did not think of before the 2 failed IVFs. I was positive for MTHFR (i believe heterozygous) and was told to start a Rx prenatal vit with increased folic acid, plus 2 folic acid supplements, and asa81 mg.
