I'm pregnant and terrified.

Well, I guess the title says it all.  Got my BFP yesterday; doctor won't see me for 3 weeks.  I'm absolutely terrified.  My husband and I both want this so much.  I can't believe it's real.  But I'm so scared.  This will be our first child.  I'm terrified of pregnancy as well as labor..  so terrified of labour.  Also once the baby is born.  I'm scared of being a bad mom.  I've never taken care of anyone else before.  This is all so new and scary.  Has anybody else ever felt this way?
