Impending miscarriage

Laura 1 Son 3 Angels 🌈 due 3/28/2020

I was told yesterday at my 7 week ultrasound that the baby isnt growing quickly enough. Possible heartbeat at 95. I was told to wait a week and come back, but told what to do when I start to miscarry.

I'm laying here so confused. Do I just lay here for a week?

My husband and I just keep crying, and I want this time to pass already.
