100% pro-life (NO EXCEPTIONS!!), and I'd probably write someone in this year if this issue weren't so important to me.
If you could save either a tray of 1,000 fertilized human embryos or a baby from a burning building, which would you choose? Keep in mind that you just said NO EXCEPTIONS.
I would save the 1000 lives (provided they weren't being held for research or something, but were actually being allowed to continue to live and develop), but I hate these sorts of theoretical questions that are unlikely to happen. Also, this is why I oppose IVF- they make countless lives and just discard most of them.
