I've never had a miscarriage but can feel your pain through your post. When I was going through testing for a serious disease, I was under considerable stress and ended up getting sick because I was so stressed out. I had to call parents and they were very understanding, even a parent that desperately needs daycare. Our clients have to realize that we're only human and we have to occasionally take time for ourselves. Just remember that if you don't take care of yourself, there will be no dch.
