So freakin' scared...

I am so afraid that I'm going to miscarry this baby. I'm 7 weeks and 3 days today. I'm trying to be so positive but I have type 2 diabetes (pre-existing) & my sugars are EVERYWHERE. My family Dr literally told me I have an 86% chance of losing my baby without running ANY tests. I was crying so hard when I left her office I couldn't drive. My husband was pissed, but held me and said to not let her attitude effect mine. I see the OB's nurse on the 20th and hopefully hear the heartbeat and then my ultrasound and the meeting of my OB is the 30th. I'm so afraid they won't find a heartbeat and I'll have to deliver another stillborn....please send blessings.
