"What about a miscarriage? What do I look for?" I asked my doctor as I was leaving her office the morning I discovered I was pregnant. She never once brought it up. I almost forgot to. "Oh, right. Yes, that could happen. It does happen." She seemed uncomfortable. "There's about a 20 to 30 per cent chance it will happen. Call me if you have intense cramping with bleeding at the same time. Some spotting is normal, as is some cramping. But they shouldn't happen together." Later when I told my girlfriend how much that stat had terrified me -- 20 to 30 per cent -- she laughed it off. "No, that means there's a 70 to 80 per cent chance it WON'T happen! You have to think of it that way." So I did. I knew friends of friends who'd had miscarriages, but it wouldn't happen to me.
