TW** Miscarriages and Heaven

I believe babies go to Heaven if they are aborted or miscarried, but at what point do you think a baby has a ‘soul’ and goes to Heaven?

For example, I fully believe if a miscarriage happens later on in the pregnancy that the baby goes to Heaven. However, what about early miscarriages? I’m talking 5-6 week miscarriages. Sperm and egg has met, but do you consider it a baby or an embryo? If you consider it an embryo and think it does not go to Heaven, at how many weeks do you think it is considered a baby and goes to Heaven if it dies?

Any supporting scripture? I’ve just been thinking about it a lot since my early miscarriages and not really sure what I believe.
