Scared...

I have always wanted to be a mom and couldn't go through life without trying again after 3 miscarriages but I've always been so scared. Not of being a mama but of birth. I know we are born to do this but am I the only one? My new hubby is so understanding and I know he will be my rock thru this but why am I so scared? I think it goes back to me hearing many many years ago about a friend of a coworker of mine dying from childbirth. I know I have to be positive and trust all will work out but does anyone else feel this way? I'm 5 weeks today!
