Elarwood if it me I would transfer the 2 best ones & grow out the morulas to see how they fair. You said that you weren't worried by the possibility of twins!!! Tough decision...good luck!!!

For both of my stim cycles I got 9 eggs. From the first, 6 were good enough for testing & I only got 2 that came back normal. First one from a fresh transfer resulted in my DD & the other was a FET which resulted in a m/c @ 9 weeks. From my 2nd stim only 5 made it to testing but only 1 came back normal which was a chem preg from a fresh transfer. Have no idea what the grades were of the first two but I think the third transfer was a 2A. Hoping for much better stats this cycle!
