I want to throttle people who imply that there is any blame attributable to the woman. It's amazingly difficult to disrupt a healthy pregnancy, and almost impossible to preserve one that isn't going to make it.

I continued to train in kung fu through the 8th month of my first pregnancy, although I didn't take any falls after about 4 or 5 months. I knew women who practiced aikido right up until the end of their pregnancies. My doc said, "Just don't do anything to break your pelvis. You probably won't lose the baby even so, but it's miserable to be pregnant and be laid up that way."
