My first IVF cycle I was on CoQ10. Afc was 9-11. Got 4 mature eggs. FSH was 16.7. This cycle I had been off the Coq10 for about 4 weeks. AFC was the same but got 8 mature eggs and FSH was 15. The only thing I added this cycle was a bit of extra vitamin D and more time in the sun. I know Jamie responded poorly to the coq10 if I'm not mistaken.
But this is a real head scratcher. Your AFC is still pretty decent though.
