As you probably know, miscarriages are very common; more than one in eight pregnancies ends in an early loss. The most common reason for a miscarriage is that your one-in-eight number came up.

The chance for success the next time around is good. But don't be surprised if you feel extra-anxious about it.

Miscarriage is very common -- on average, about 1 in 8 pregnancies ends before the 10th week. Age plays a great role in this risk, though; the chance of miscarriage at 40 is about 1 in 5, and at 45 is 50 percent.
