Hmmm, I'll have a crack at it!
I play quite conservatively. I like Option 1, because it gives you three cracks at trying to get pregnant. I know it is more costly but you've done a few double transfers now and I wonder if you might have better luck with singles?
I don't like Option 5, purely because you're basically throwing away a potentially good embryo.
It's really your choice though hon - you have to do what you're comfortable with
