Scared I'll never get it...

Mi
After having my miscarriage I really am scared.  I can't picture myself being pregnant and I'm scared that somehow I'll never go through and make it to full term.  They tested my blood at the doctors and I was B+ therefore making it so I most likely shouldn't have problems with a future pregnancy. But I'm so scared.  Anybody feel this way and went through to full term? I need any encouragement
