Since the moment of his birth, my 5-year-old son has been a near unalloyed joy, but the long journey to that moment was anything but joyous. My husband and I started trying for a child in 2013, and I quickly became pregnant. At 10 weeks, I had an unexplained miscarriage. I was rushed to the emergency room where I ultimately had a dilation and curettage, or D&C, to clear my womb of the self-aborted pregnancy.
