Research shows that 50% of all (including the first 2 weeks when people don't know they are pregnant and never know they were) pregnancies end in miscarriage. That number drops to around 10-25% after the 3rd week. Women in there 20s-30s are around 10-15, while 35+ is about 25%. 80% of all miscarriages happen in the first 12 weeks. After 12 weeks or the first trimester the chance of miscarriage drops to around 1-3% depending on age and health of the mother.
Hope this helps.

In over half of all miscarriages, the fetus is abnormal. The abnormality can either be genetic or developmental.
So many women have miscarriages that it is unlikely. If you both had recurrent miscarriages and neither of you have had a baby it is possible but still unlikely. i dont have an answer to that but my husband's ex had a miscarriage and so did I.

Dreaming that you are pregnant and you have had miscarriages is not a sign or pointer to future troubles, as you can still have babies.
