If you're newly pregnant and trying to make sense of the myriad statistics about miscarriage , here's an explanation of each one that may ease your mind.

If taking into account the number of known miscarriages and the number of unknown miscarriages, there is a greater chance of miscarriage than not.

It usually goes entirely unnoticed, often because it occurred within days of the conception and the pregnancy was non-viable from the start.

In real life, most women find out they are pregnant at a later point than the participants in this study, and the risk of miscarriage drops as pregnancy progresses. That would mean that most women have a lower risk of miscarriage by the time they confirm their pregnancies. Many experts cite this statistic as an argument against taking ultra-sensitive early pregnancy tests before missing a menstrual period.
