Of course you have the right to be sad for your lost daughter. And to be afraid of this pregnancy too.
Your doctors will be keeping an extra close watch on you this time to try to avoid any other complications. Tell them how you feel, maybe even see a psychiatrist to help you through.
Good luck to you and your family, and this little miracle too.
You have a valid reason for fearing for this child.. There was nothing you could have done differently.. I hooe this pregnancy goes so much better for you love..
