As many as 75% of miscarriages occur in the first 3 weeks or so, before a woman even knows she is pregnant. As many as 25% of pregnancies end in miscarriage before 12 weeks, with the rate being slightly higher for women who are older.
A systematic review found that the cumulative risk of miscarriage between 5 and 20 weeks of gestation varied from 11% to 22% in studies assessing miscarriage rates. Up to the 13th week of pregnancy, the risk of miscarriage each week was around 2%, dropping to 1% in week 14 and reducing slowly between 14 and 20 weeks.mong women who know they are pregnant, the miscarriage rate is roughly 10% to 20% while rates among all conceptions is around 30% to 50%.
