They are right, enjoy the
process. The text book answer for a
miscarriage is 20% of all pregnancies, really it's about 35% when we consider known and unknown pregnancies. The majority of these being in the first trimester. The rate drops significantly with a heart beat and then achieving 10 weeks gestation. All kinds of numbers and miscarriage rates are running around out there after a heart beat is seen, I have seen from 5 to 10% quoted.
