Needing Moral Support!

I found out two days ago I am pregnant, so I called the doctor and he's estimating the first week of December for the due date. I am so excited, but I can't help but be scared to death!!! This is my first pregnancy and I know the chance of a miscarriage are real! How did you or how are you getting through this stage of fear?? Thank you for the advice! So far everything is happy and healthy!
