Possibly pregnant

Amber
So I had a MC 2 months ago at 12 weeks.... Had a normal period last month. Well AF was due to start on Sunday but nothing yet. I took a test today and got this 
I'm just super nervous and don't want to get my hopes up.  I'm gonna test again on Friday and if I get another positive I am going to call my Dr. Any advice to help me not be so nervous? I have already had two MC before.
