This is my understanding.

From auras, I can detect pregnancy and various stages enroute such as:
1. Energy gathering (sperm takes a few hours to reach egg).
2. Conception which may not lead to implantation.
3. Implantation which may later be reversed by the body.
4. Soul descent after 20 weeks but sometimes not at all - which causes some cases of SIDS.

@Felynx, did you perceive any soul descent prior to 20 weeks?

@forevergirl, this is a delicate area and the statement "that my Dad was taking care of him" doesn't give me much confidence that your reader was qualified to comment.
Souls are immortal. We have had thousands of lives and thus hundreds of families.

I'm not qualified either, especially without personal contact. I only have to think of sensing chlldren's spirits and hundreds flock to me...
