what to do with my frozen embryos?

After having three successful rounds of IVF at various different points in life. I have spare frozen embryos. It is highly unlikely that I will ever get pregnant again. 4 children is enough for me. As a Christian I've been told that I shouldn't get rid of the embryos cause it's a human life. I will never understand why so many people feel like they can have an opinion on my uterus and what it gets up to. I was wondering if anyone has gone through this experience or thought about what they would do in this situation. I don't considered the embryo as a life. It's just something in a fridge somewhere. I only make that emotional connection later. It's also really expensive to keep them frozen
