There is a lot of talk on the Internet about how in the first 12 weeks of pregnancy has the highest risk of miscarriage and the chance is 1 in 6.
Is it correct to assume though that healthy people are less than a 1 in 6 chance? And unhealthy people who drink, smoke, don't excersise and are fat etc are more than 1 in 6?
Or is the 1 in 6 chance based on "if you are healthy"?
