19 weeks and not showing.

Aimie • Live on the farm with my sister and niece. 🎀
I'm worried. My baby bump is nothing compared to everyone else I see. I have no movement from the baby.
I'm worried. I have a scan in a week. I've had no spotting but all of my symptoms have gone. I don't want to lose another baby. I'm so scared and I'm sure my SO won't love me anymore. I've had 3 previous previous  miscarriages. 
Any advice?
