I think it's normal to miss pregnancy, it's such an beautiful and intimate time only you and your baby share. I missed it some after being pregnant, but I was so glad the discomfort was over, it didn't last long.
You will be going through a million different feelings after the birth due to emotions, hormones, etc. My son was in the NICU for 4 days, and we went throught the roller coaster of "Is he OK, Is anything wrong with him, Will he come home with us". Even after all this, when we did take him home, I remember looking at him in the car seat and thinking "Oh my, what do I do with him now". I went through a few days crying thinking "Nothing will ever be the same, I will always have this huge responsibility, I won't be as free as I once was" even though my husband and I were extatic over his arrival and being parents. I was terrified of him the first couple of days, not knowing what to do and wondering if I was doing it right, and being scared I was a bad mother because of all of these thoughts and fears.
I would advise that you have a family member or someone stay with you after you come home to help you with the baby and help you get rest. You are new at being a mother, and you may not realize it, but your baby is new at being alive, so not only are you adjusting, but she will be adjusting to the shock of life outside the womb as well.
One thing I have learned, the fear that something will happen to your child will never go away. She is your most vunerable and exposed nerve now. I still worry about my son even when I know he is safe at home with my husband or my mother. It sounds like you are religous, as am I, so I just pray sonstantly for him. Your fears in that area probably will never go away completely, but will decrease as she gets older and less helpless. Congrats and God Bless!
