Nervous Beyond Belief

One of the women I work with was 4 months pregnant and went to get an ultrasound. As it turns out, the baby has been dead inside of her for about a week and she has to carry it for another week before it can be removed. 
I'm currently TTC #1 and the thought that this happens to people after they have been carrying a child and been so blessed absolutely horrifies me. I'm so scared that this will happen and it makes me not want to even try anymore. I don't think I could handle that kind of heartbreak.
