Hello Butterfly I am so very sorry about your loss. i hope someone can come up with answers for you.
I had a m/c where the baby appeared to stop growing at 5 weeks but i held on to it until 12 weeks. My DH said to me (trying to make me feel better) that it wasn't really a baby because the cells hadn;t divided and it hadn't gotten a heartbeat. I remember wanting to slap him across the head because whether cells had divided or not, i was pregnant and now i wasn;t. That is a loss of a baby any way you look at it.
Take care Butterfly Warrior xo
