When does life start?

Stacey • Living with recurrent miscarriage, married for 3 years, LDS, and a pre-k teacher.
First off, I'm so excited I found a group of LDS women on here! I use the social part of Glow mainly for loss support, but it's so nice to find a group I can relate to that doesn't always revolve around loss 😊
I'm curious when you ladies think life starts. I've had 3 miscarriages and just consider them to be my children who have completed their mission in life and are now waiting on the other side. But when I really stop to think about it, I have to question it. I never saw the babies or a heart beat, and only knew was pregnant because of symptoms and pregnancy test results. 
I rely heavily on the fact that I'll finally be able to hold each one of them one day. I guess I just want to make sure I don't get my hopes up, only to get to the other side and find those pregnancies were lost because there was no spirit ready to join our family.
