I completely understand where you're coming from! We struggled with the situation as well. We knew we would do IVF, we just worried about getting too many embryos. We told ourselves up front we would give life (or try to) to any embryos we made. And we just prayed we would be wise about our decisions and God would be in complete control.
We got 20 eggs. Easily that could have become 15-20 embryos. So we opted to only ICSI 12 and to let the other 8 try naturally (we have a sperm penetration issue so we knew we weren't going to get super lucky with all 8 fertilizing).
In the end we only got 4 embryos. Only 2 that made it to our 3 day transfer. So we had no frozen embryos.
But I have to be honest with you, when you hear how many embryos you have growing, there is an instant connection. They are your "children". So many women have said the same thing. You feel protective of them and you want the best for them. So I think it would be hard to disregard them, unless that's your stance going into it.
But for us no matter how hard pregnancy would be or how much it would cost, we promised we would give a fighting chance to any embryos we created. My husband and I believe that once the egg and sperm meet, life has begun and that wasn't up to us to decide what to do with those precious lives we created. We could never have given the ok to destroy them. It just wasn't an option for us. And now that we have our baby and we look at him and remember where he started, I'm not quite sure how people could see it any other way.
So pray pray pray through the process that God will guide you and the entire process. We felt 20 eggs was just too much of a risk. Obviously it didn't turn out that way for us, but we couldn't have known that going into it.
And I wouldn't go into the situation without complete peace that it's what God wants for you!
