Hun,
I know how hard it is to not be overwhelmed by the anxiety when you've lost bubs before. I guess all I can say is unfortunately it doesn't get easier until you start feeling your bub moving in your belly. Try to have faith in your bub, he/she is healthy in there & doing what they should be doing!
Even now I have only 5 weeks to go & I'm scared daily for her safety. I think the constant worry won't leave us until we are holding our babies in our arms.
Try not to worry Hun, your little one will be fine xox
