Anxiety!

Is anyone else feeling extremely anxious about there baby's safety in the womb? I am high risk and things just keep going wrong and I find myself constantly worrying about my son. I talked to my doctor about this and he said it's completely normal to be anxious and worried, but I feel like I shouldn't be this worried. I did get to see my sweet boy the other day and he is still growing really well, which is such good news.
